0.21 is a very old version for the EnvInject plugin.
Each new version keeps backward compatibility (at least in theory, i try).

Maybe, I missed a thing with the dostrigger plugin.

I can try to reproduce the problem.
Please could you attach your job configuration file (confg.xml)?

Hi Gregory

We know 0.21 is old, but it is working
1.72 is giving the problem. I have tried to reproduce it on my PC (Win XP) without success.
I can only get the error on the Windows 2008 Server Enterprise with Service Pack 2.
Now we are running with 0.21 without problems. I can't test a lot of things as a lot of colleagues depends on the server running.

I have tried googling the error and it indicates that classpath is more than 8191 characters. I don't know if this can help you in any way.

Building the job below has no problems calling hg, but the polling every minute fails with the error.

I have the same problem, however this happens only on master and only when I use in combination with Node and Label parameter plugin (e.g. set the node as "master"):

Build step 'Execute Windows batch command' marked build as failure
Finished: FAILURE

I'm afraid I'm closing the issue because I can't reproduce it.
Please try to isolate the problem from the other plugins and raise a new issue.

I was able to reproduce exactly this error.
New newly created and almost empty job kept failing. So I started analyzing the cause.
It is a parametrized build job like Jakob's but I can't see a related configuration issue in his config.xml.

In my case was a parameter with a value.
The message is not very clear about it, but maybe it helps you to track down the cause if you should run into a similar message.

Linked the issue with JENKINS-22183, where the same issue appears in jobs, where custom-tools and envinject work together.

I'm not sure the issues are duplicates but I hope it will provide some additional info for analysis
