Could you attach your job configuration file (config.xml)?

Note that in the attached config.xml the environment variables (EVVERSION among others) are manually duplicated in the make-release batch task (to make it work)

Fix JENKINS-13647

The use of EnvVarsResolver in that commit seems to cause a blocker issue when running a batch task. Nothing happens on the GUI, the console is empty, here's the server log stacktrace:

hudson.model.Executor run
SEVERE: Executor threw an exception
java.lang.NullPointerException: Current Project is null
        at com.sonyericsson.rebuild.RebuildAction.getProject(RebuildAction.java:117)

        at hudson.model.Executor.run(Executor.java:239)

Tested with Jenkins 1.460 and 1.463

According to the trace, it is due to the rebuild Jenkins Plugin

AbstractProject currentProject = null;
StaplerRequest request = Stapler.getCurrentRequest();
if (request != null) {
 currentProject = request.findAncestorObject(AbstractProject.class);
}
if (currentProject == null) {
 throw new NullPointerException("Current Project is null");
}

Fix for JENKINS-13647
Avoid NullPointerException on the getProject() method when getURL() method is call from a content where your can't retrieve a Project object in the request (such as in the batch-task plugin)

Fixed.
The error was not due to the EnvInject plugin.
EnvInject plugin only participates to have an isolate build by managing environment variables.
The Batch-Task plugin delegates environment variables to the EnvInject library. The library is embedded in the batch-task plugin distribution (the installation of the EnvInject plugin is not required).
EnvInject library calls programmatically all build actions. In your use case, these actions contained an action from the rebuild plugin.
And RebuildAction object threw an exception when the project object can't be retrieve from the request (the use case in the batch-task plugin context).
I fixed it in the rebuild plugin.
Please upgrade to rebuild plugin 1.11.

Still got the issue with Jenkins 1.465, batch task plugin 1.16, rebuild plugin 1.11:

Rewrite getURL() to fix a NullPointerException

Reproduced again with Jenkins 1.472, Batch task 1.16 and Rebuilder 1.14:

Downgrading again to Batch task 1.15 as a workaround.

I dont think I use rebuilder

mine is

There is an issue for recent Jenkins core version.

Jenkins ver. 1.515
Environment Injector Plugin 1.86
Jenkins batch task plugin 1.17

Build describes env vars on "Prepare an environment for the run". There is injectedEnvVars.txt and there is the env var there. But run of batch task does not load them.
