java.lang.IllegalArgumentException: value already present

[codeseedr]

I just hit an issue with two dependencies that try to declare jdk tools jar as a dependency. Both do it a bit differently because they use different coordinates: one (org.jolokia:jolokia-jvm:jar:agent:1.5.0) -- com.sun:tools:1.8, and the other (org.neo4j:neo4j-dbms:3.4.11) -- jdk.tools:jdk.tools:1.6. As you probably imagine, they're both scope=system deps with systemPath=${java.home}/../lib/tools.jar.

In the above described environment plugin execution fails with:

java.lang.IllegalArgumentException: value already present: /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/jre/../lib/tools.jar

Thanks, I will investigate this.

I have a basic fix for this; there are some challenges with the system classpath that I need to work through. I should be able to cut a new release some time this week.

Sounds good, thanks!
