I have spring boot application in my github public reposity. I have used gradle as a build tool for this spring boot application. I am using jenkins as CI/CD.
I have below task in my build.gradle file which is used to auto-increment the build number so that my generated executable jar will have unique version name in the generated jar file.
task versionIncr {
Properties props = new Properties()
File propsFile = new File('gradle.properties')
props.load(propsFile.newDataInputStream())
Integer nextbuildnum = ( ((props.getProperty('artifactBuildNumber')) as BigDecimal) + 1 )
props.setProperty('artifactBuildNumber', nextbuildnum.toString())
props.store(propsFile.newWriter(), null)
props.load(propsFile.newDataInputStream())
}
i am calling this task in jenkins as below.
"versionIncr bootJar docker --warning-mode=all"
this task is working perfectly. As a result of this task below is happening in jenkins server
- jenkins pulling the git $branch into the jenkins server workspace
- task =>
versionIncris getting executed and incrementing the version number and updating"gradle.properties"file in the workspace that is there in jenkins server - generating executable jar file
- creating docker image with the newly generated executable jar file
problem::
the changes made to "gradle.properties" file are left in the jenkins server workspace and the updated version number will not gets reflected in the git hub branch. since jenkins made changes locally so when i push any changes to the github and run the jenkins job then version number in "gradle.properties" file will still remains same. I do not want to update the version number manually each time i push my commits. I want jenkins to handle the version change for me.
is there any way or gradle plugin or jenkins plugin which i can use to push the modified "gradle.properties" file from jenkins workspace back to "github" repository.
Also if possible i would like to know the way of achieving using either github username/password or by using SSH.
let me know if i need to post any more information here.
Update:: Posting my build.gradle file just in case if some one is interested in how i am doing it. build.gradle
