Createprocess error=206; the filename or extension is too long

Question

I know this question has been asked before, but I wasn't able to fix it using solutions from other posts. I'm trying to compile a complex hierarchy of gwt projects using maven. Everything worked fine until I had to add one more library, more specifically: org.eclipse.birt.runtime

Now I get this error:

[ERROR] Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.6.1:debug ....

..... [Lots of jars, many containing birt, no duplicates though] .....


Error while executing process. Cannot run program "C:\Program Files\Java\jdk1.8.0_20\jre\bin\java": CreateProcess error=206, The filename or extension is too long

The dependency I'm using is:

<dependency>
    <groupId>org.eclipse.birt.runtime</groupId>
    <artifactId>org.eclipse.birt.runtime</artifactId>
    <version>4.4.1</version>
</dependency>

Answer 1

I finally managed to solve it:

Turns out birt, together with its dependencies, was simply adding too many libraries and the classpath became too long for windows command to handle. Furthermore, birt libraries have stupidly long names.

Solved it using this dependency (I only needed the runtime), I created the lib and birt directories and placed the jar there myself:

<dependency>
    <groupId>org.eclipse.birt.runtime</groupId>
    <artifactId>org.eclipse.birt.runtime</artifactId>
    <version>4.4.1</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/birt/birt.runtime-4.4.1.jar</systemPath>
</dependency>
