i need to write jenkins step, that will push to svn file converted_assets.json if it changed
To write a Jenkins step that will push a file to SVN if it has changed, you can follow these steps:
Install the Subversion plugin for Jenkins. This will allow Jenkins to interact with your SVN repository.
In your Jenkins pipeline, you can use the svn command to check if the file has changed. For example:
def file = 'converted_assets.json'
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} -m 'Updating converted_assets.json'"
}
This will run the svn diff
command to check if the file has been modified, and if it has, it will commit the changes to the SVN repository.
Note that this script assumes that you have already run svn update
to get the latest version of the file from the repository and that you have made your changes to the local copy of the file. You may also need to adjust the SVN command depending on your specific SVN setup and workflow.
what happens if converted_assets.json does not exist?
If the file converted_assets.json
does not exist, the svn diff
command will return an error indicating that the file does not exist in the repository. This will cause the sh
command to fail, and the pipeline will stop.
To handle this scenario, you can add a check to see if the file exists before running the svn diff
command:
def file = 'converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} -m 'Updating converted_assets.json'"
}
} else {
echo "File ${file} does not exist. Skipping commit."
}
Alternatively, you can use the svn add
command to add the file to the repository if it does not already exist:
def file = 'converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} -m 'Updating converted_assets.json'"
}
} else {
sh "svn add ${file}"
sh "svn commit ${file} -m 'Adding converted_assets.json'"
}
This will add the file to the repository if it does not already exist, and then commit the changes.
i have this structure of BuildType: bash { name = "Commit in SVN" conditions { equals("commit_in_svn", "true") } scriptMode = script { content = """ """ } } Should i put your code inside content?
Yes, you can put the code I provided inside the content
field of the script
block.
Here is an example of how you can incorporate the code into your Jenkins pipeline:
bash {
name = "Commit in SVN"
conditions {
equals("commit_in_svn", "true")
}
scriptMode = script {
content = """
def file = 'converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} -m 'Updating converted_assets.json'"
}
} else {
sh "svn add ${file}"
sh "svn commit ${file} -m 'Adding converted_assets.json'"
}
"""
}
}
This will run the script only if the condition equals("commit_in_svn", "true")
is met. You can adjust the condition and the script as needed to fit your specific requirements.
Note that you will also need to make sure that the Subversion plugin is installed and configured properly in Jenkins, and that you have authenticated with the SVN repository using the svn login
command or by providing the necessary credentials in the Jenkins configuration.
i've just realized, that my svn inside 'data_svn' folder. how to rewrite the code?
To modify the code to work with a Subversion repository located in a subdirectory, you can simply specify the path to the repository in the svn
commands.
For example, if your Subversion repository is located in the data_svn
directory, you can use the following code:
bash {
name = "Commit in SVN"
conditions {
equals("commit_in_svn", "true")
}
scriptMode = script {
content = """
def file = 'converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize data_svn/${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit data_svn/${file} -m 'Updating converted_assets.json'"
}
} else {
sh "svn add data_svn/${file}"
sh "svn commit data_svn/${file} -m 'Adding converted_assets.json'"
}
"""
}
}
This will run the svn
commands on the repository located in the data_svn
directory.
Note that you will need to make sure that the working copy of the repository is checked out to the correct location in your Jenkins workspace. You may also need to adjust the svn
commands depending on your specific SVN setup and workflow.
that's no correct, because converted_assets.json is also in data_svn folder
If the file converted_assets.json
is also located in the data_svn
directory, you can simply specify the path to the file in the svn
commands.
Here is an example of how you can modify the code to work with a file located in the data_svn
directory:
bash {
name = "Commit in SVN"
conditions {
equals("commit_in_svn", "true")
}
scriptMode = script {
content = """
def file = 'data_svn/converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} -m 'Updating converted_assets.json'"
}
} else {
sh "svn add ${file}"
sh "svn commit ${file} -m 'Adding converted_assets.json'"
}
"""
}
}
This will run the svn
commands on the file data_svn/converted_assets.json
in the repository.
Note that you will need to make sure that the working copy of the repository is checked out to the correct location in your Jenkins workspace, and that the file converted_assets.json
exists in the data_svn
directory. You may also need to adjust the svn
commands depending on your specific SVN setup and workflow.
are you sure that commands 'svn add' and 'svn commit' will work, if svn repository in the subfolder?
Yes, the svn add
and svn commit
commands should work properly for a Subversion repository located in a subdirectory. The svn
command line client is designed to operate on a working copy of the repository, and the path to the repository is determined by the current working directory.
In the example code I provided, the svn
commands are run from the Jenkins workspace, which is typically the root of the working copy. As long as the working copy is checked out to the correct location in the Jenkins workspace, and the file converted_assets.json
exists in the data_svn
directory, the svn add
and svn commit
commands should work correctly.
If you are having trouble with the svn
commands, you may want to check the following:
Make sure that the Subversion plugin is installed and configured correctly in Jenkins.
Make sure that you have authenticated with the SVN repository using the svn login command or by providing the necessary credentials in the Jenkins configuration.
Make sure that the working copy of the repository is checked out to the correct location in the Jenkins workspace.
Make sure that the file converted_assets.json exists in the data_svn directory.
If you are still having trouble, you may want to try running the svn
commands manually from the command line to see if there are any issues with the repository or the working copy.
ok, remove condition "commit_in_svn" and add credentials to svn --username jenkins \ --password %system.svn_pass%;
To modify the code to remove the condition and add credentials to the svn
commands, you can use the following code:
bash {
name = "Commit in SVN"
scriptMode = script {
content = """
def file = 'data_svn/converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} --username jenkins --password %system.svn_pass% -m 'Updating converted_assets.json'"
}
} else {
sh "svn add ${file}"
sh "svn commit ${file} --username jenkins --password %system.svn_pass% -m 'Adding converted_assets.json'"
}
"""
}
}
This will run the svn
commands without the commit_in_svn
condition, and will include the --username
and --password
options to specify the credentials for the SVN repository.
Note that you will need to make sure that the working copy of the repository is checked out to the correct location in your Jenkins workspace, and that the file converted_assets.json
exists in the data_svn
directory. You may also need to adjust the svn
commands depending on your specific SVN setup and workflow.
i think there is something wrong with your {} parents. we should add file to svn only if file exists
You are correct, there is an issue with the curly braces in the code I provided. To fix the issue and add the file to the SVN repository only if it exists, you can use the following code:
bash {
name = "Commit in SVN"
scriptMode = script {
content = """
def file = 'data_svn/converted_assets.json'
if (fileExists(file)) {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} --username jenkins --password %system.svn_pass% -m 'Updating converted_assets.json'"
}
}
"""
}
}
This will check if the file converted_assets.json
exists in the data_svn
directory, and if it does, it will run the svn commit
command to push the changes to the SVN repository. If the file does not exist, the script will not run the svn commit
command.
Note that you will need to make sure that the working copy of the repository is checked out to the correct location in your Jenkins workspace, and that you have authenticated with the SVN repository using the svn login
command or by providing the necessary credentials in the Jenkins configuration. You may also need to adjust the svn
commands depending on your specific SVN setup and workflow.
handle the case where file exists but did not added to the svn
To handle the case where the file converted_assets.json
exists but has not been added to the SVN repository, you can modify the code to check if the file is already under version control using the svn status
command.
Here is an example of how you can modify the code to handle this case:
bash {
name = "Commit in SVN"
scriptMode = script {
content = """
def file = 'data_svn/converted_assets.json'
if (fileExists(file)) {
def svnStatus = sh(script: "svn status ${file}", returnStdout: true).trim()
if (svnStatus == '?') {
// file is not under version control, so add it to SVN
sh "svn add ${file}"
} else if (svnStatus == 'M') {
// file has changed, so push it to SVN
sh "svn commit ${file} --username jenkins --password %system.svn_pass% -m 'Updating converted_assets.json'"
}
}
"""
}
}
This will run the svn status
command to check the status of the file converted_assets.json
in the working copy. If the file is not under version control (indicated by a status of ?
), it will run the svn add
command to add the file to the repository. If the file has been modified (indicated by a status of M
), it will run the svn commit
command to push the changes to the repository.
Note that you will need to make sure that the working copy of the repository is checked out to the correct location in your Jenkins workspace, and that you have authenticated with the SVN repository using the svn login
command or by providing the necessary credentials in the Jenkins configuration. You may also need to adjust the svn
commands depending on your specific SVN setup and workflow.
should not we use 'svn add' with credentials?
In general, it is not necessary to use the --username
and --password
options when running the svn add
command. The svn add
command operates on the local working copy, and does not require authentication with the SVN repository.
However, if you are using the svn add
command as part of a script that is run by Jenkins, you may need to specify the credentials in order for the script to have permission to modify the working copy. In this case, you can include the --username
and --password
options in the svn add
command as follows:
sh "svn add ${file} --username jenkins --password %system.svn_pass%"
This will include the credentials in the svn add
command, which may be necessary depending on your specific SVN setup and permissions.
Note that you will need to make sure that the working copy of the repository is checked out to the correct location in your Jenkins workspace, and that you have authenticated with the SVN repository using the svn login
command or by providing the necessary credentials in the Jenkins configuration. You may also need to adjust the svn
commands depending on your specific SVN setup and workflow.
what if the file exists but did not changed? did we handle this situation?
In the code I provided, the svn commit
command will only be run if the file converted_assets.json
has been modified, as indicated by the svn diff
command. If the file has not been modified, the svn commit
command will not be run.
If you want to handle the case where the file exists but has not been modified, you can add an additional check to the code to see if the file has been modified before running the svn commit
command.
Here is an example of how you can modify the code to handle this case:
bash {
name = "Commit in SVN"
scriptMode = script {
content = """
def file = 'data_svn/converted_assets.json'
if (fileExists(file)) {
def svnStatus = sh(script: "svn status ${file}", returnStdout: true).trim()
if (svnStatus == '?') {
// file is not under version control, so add it to SVN
sh "svn add ${file}"
} else {
def svnDiff = sh(script: "svn diff --summarize ${file}", returnStdout: true).trim()
if (svnDiff) {
// file has changed, so push it to SVN
sh "svn commit ${file} --username jenkins --password %system.svn_pass% -m 'Updating converted_assets.json'"
}
}
}
"""
}
}
This will run the svn diff
command to check if the
