Not sure what the issue is here.

Exception thrown:

@PaulKlint this one was solved right? With the upcoming rascal core release?

[PaulKlint]

I suspect it is caused by the target scheme that is not yet supported in the main branch.

[DavyLandman]

The target scheme has been around for a while, I thought this was a duplicate of #529 ?

[PaulKlint]

It is indeed a duplicate of #529.

One observation: target://bas2-maintainability-model should be target:///bas2-maintainability-model (but this does not solve the problem).
Other observation: isDirectory(|target:///classes|) yields false although it does exist.

My suspicion is still the target scheme.

[DavyLandman]

Target behaves like the project scheme, so it should have the project name in the authority. Target refers to the target folder in a specific project.

But we could have missed some cases in how the resolver behaves.

[PaulKlint]

More observations:

rascal>mkDirectory(|target://rascal-core/XX|);
ok
rascal>isDirectory(|target://rascal-core/XX|);
bool: true

BUT

the directory has been created in |target://rascal-core/classes/XX| !!

This explains at least why the .tpl file could not be written.
