Fred,
you did not describe how exactly you solved the problem. You just
mentioned properties of which there are several types, which is why your
answer is unclear:
-- literal Maven properties which you tried to use before
-- '<properties>' for the GMplus 'execute' goal
-- properties implicitly bound inside GMPlus scripts
Using the latter, you could just directly use 'project.basedir' (which
yields a File instance already) and the corresponding File constructor:
new File(project.basedir, "src/main/javascript/gremlin-javascript/package.json")
Of if you do want to use the File(String) constructor:
new File("$project.basedir/src/main/javascript/gremlin-javascript/package.json")
Probably you meant something like this, but let us close this thready
with an explicit answer, just for reference.
As for why the "${project.basedir}" syntax yields problems inside the
Groovy script: It is because Maven already expands the expression, so
the Groovy parser sees an illegal string literal with single, unescaped
backslash characters. You can see this on the console when running your
Maven build with debug output.
