> The problem is that the code is attempting to create a temp file underneath
> the {{gremlin-test.jar}} file located in the local {{$HOME/.m2/repository/}}
> directory.
> One workaround is to use a {{build.dir}} property, and this is documented in
> the source code, see
> [this|https://github.com/apache/incubator-tinkerpop/blob/3.2.0-incubating/gremlin-test/src/main/java/org/apache/tinkerpop/gremlin/TestHelper.java#L99-L103]
> and
> [that|https://github.com/apache/incubator-tinkerpop/blob/3.2.0-incubating/pom.xml#L1007].
> The fix I'm proposing is to use the graph implementation class instead of the
> test class as the root of the build directory. Since the tests are typically
> run with the graph implementation, it will find the class under the
> {{target}} directory. Graph providers wouldn't have to do any additional
> Maven tricks to consume {{gremlin-test}}, and the existing workaround will
> continue to work.
> I'll submit a patch for this and also update the docs to make the workaround
> more visible.
