Robert Scholte updated MEXEC-108:
---------------------------------
Attachment: mexec-108-IT.patch
Consider the maven-* dependencies as {{provided}}, the version of the
dependencies you see is the minimal version required. The version of the
executing Maven are the ones used.
I've reproduced the issue with M3.0.4 and rewritten your project to an IT (
attached as patch, now only 1 file ;) ).
It looks me the plugin must check if an entry has a value. I'm not sure if
{{null}} should be ignored or passed as an empty String.

> Key: MEXEC-108

> ProcessBuilder.environment() may contain keys with a null value. In my case
> "INSIDE_NAUTILUS_PYTHON=" was defined. If maven-exec-plugin is invoked with
> the same environment variables, the following exception is thrown:
> {code}
> java.lang.NullPointerException
> at
> org.apache.commons.exec.environment.EnvironmentUtils.toStrings(EnvironmentUtils.java:66)
> at
> org.apache.commons.exec.launcher.Java13CommandLauncher.exec(Java13CommandLauncher.java:56)

> org.apache.commons.exec.DefaultExecutor.launch(DefaultExecutor.java:254)

> at org.codehaus.mojo.exec.ExecMojo.executeCommandLine(ExecMojo.java:610)
> at org.codehaus.mojo.exec.ExecMojo.execute(ExecMojo.java:352)
> {code}
> Expected behavior: EnvironmentUtils.toStrings() should be able to handle the
> Map returned by ProcessBuilder with the same interpretation as it treats null
> keys and values.
