      Description

      Empty environment variables are deleted. Three methods tried:

      1. Parameter
      2. Generate environment variables from script
      3. Inject environment variables to the build process

      As can be seen from the log below, the non-empty variables MYVAR1, MYVAR3 & MYVAR5 works as expected, but the empty variables MYVAR2, MYVAR4 & MYVAR6 are not present in the environment when the job executes.

      When looking at the enviroment through the left hand menu "Environment Variables" on the build page, all variables are present. You can actually also see that an implicit environment variable TEST_NODE is also deleted.

      I'm not sure that the problem is in EnvInject. Feel free to move it to some other component.

      Looks similar to JENKINS-15146.

            The config in the description was wrong, but I've edited it so it is now the correct one.

            Also affected by this.

            I use an environment variable to add a "-dev" suffix to any branch when a boolean DEV is set to true. These suffixes do not work when building for production and they need to be empty.

            Any chance for this to be fixed? Any workarounds available? Sometimes the empty env variables must be set for third-parties that really relies on them...
