Hi all,
I want to call a script from my maven build so I use the maven-exec plugin
for this. The script I want to call calls in turn at some point java and
all environment variables are transmitted. I would like to override
JAVA_TOOL_OPTIONS and define an empty value for it so I used the following
configuration:
<execution>
<id>gulp-build</id>
<phase>process-resources</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>gulp</executable>
<failWithNullKeyOrValueInEnvironment>false</failWithNullKeyOrValueInEnvironment>
<environmentVariables>
<JAVA_TOOL_OPTIONS/>
</environmentVariables>
<workingDirectory>${basedir}/src/main/resources/webapp</workingDirectory>
<arguments>
<argument>maven</argument>
</arguments>
</configuration>
</execution>
But then I end up with the same NPE that was reported in MEXEC-108 (
http://jira.codehaus.org/browse/MEXEC-108) and marked as fixed in the 1.3
version although I'm using this version:

Any idea on how to fix this and clear an environment variable without
having maven crashing?

Olivier
