Inject env vars to Jenkins programmatically

[ni...@liveperson.com]

Hi,

I am trying to inject environment variables to Jenkins build from my internal Maven plugin in Java. 

What did I do? 

I added the Jenkins code Maven dependency to my plugin an implemented the relevant interface: 

public class Test implements EnvironmentContributingAction{

       @Override

    public void buildEnvironment(Run<?, ?> run, EnvVars env) {

                EnvironmentContributingAction.super.buildEnvironment(run, env);

    }  
 }

Now - I'm trying to call this class from a different class: 

EnvVars envVars = new EnvVars();

envVars.put("myvar", "myvalue");

Test test = new Test();

test.buildEnvironment(???? , envVars);

What is the "Run" class? What should I add into this method so it will run from the build object in Jenkins? 

Any Github example or snippet will be much appreciated.

Thanks,

Nir

Hi,

I was struggling through the same type of issue and just got mine to work.  Hope this helps

My plugin 'extends' Builder.  For this to work I had to create another class 'InjectVariable'

// This is called from the Builder class I wrote
build.addAction( new InjectVariable( "VERSION_TAG", "V1.2.3.4" ) );

public class InjectVariable implements EnvironmentContributingAction {
 private String key;
 private String value;

 public InjectVariable( String key, String value )
 {
 this.key = key;
 this.value = value;
 }

 @Override
 public String getIconFileName() {
 return null;
 }

 @Override
 public String getDisplayName() {
 return null;
 }

 @Override
 public String getUrlName() {
 return null;
 }

 @Override
 public void buildEnvVars(AbstractBuild<?, ?> build, EnvVars env) {
 if( env != null && key != null && value != null )Enter code here.

 {
 env.put(this.key, this.value);
 }
 }
 }

Enter code here...
