Jenkins插件开发 - 环境变量

Question

Is there any possibility to get a map of environment variables that are used in Jenkins? I am trying to develop my own plugin and need to access the variable BUILD_USER_ID, which is provided by the build user vars plugin.

There is a class called EnvVars, which inherits from TreeMap, but it is obviously empty, if you create an object of this.

EnvVars env = new EnvVars();

Where are these variables stored , so that I can get them and use them in my plugin?

I expect you mean build variables injected by Build User Vars Plugin into build.

If you are interested in reading static jobs configuration (from system groovy script for instance), use job.getBuildWrappersList().get(org.jenkinsci.plugins.builduser.BuildUser.class) to get user configured instance of BuildUser . In case of Build User Vars Plugin there is not much configuration to read, though.

If you would like to access actual variable values injected into the build process (from a BuildStep for instance), call build.getEnvironment(TaskListener) to get populated EnvVars instance with all variables. Note that these variables are not available outside of build context.
