Creation of new project fails

[mnn]

There is something wrong with --stack-root path:

null\rikvdkleij\intellij-haskell\cache\lts-13
...
option --stack-root: InvalidAbsDir "null\\rikvdkleij\\intellij-haskell\\cache\\lts-13"

Windows 10, plugin beta57

[rikvdkleij]

Thanks for reporting!

Looks like a bug in https://github.com/soc/directories-jvm. That directory which starts with null is obtained via this library.

[mnn]

You are right, it looks like this issue. It seems some JDK changes are responsible.

Maybe try the suggested workaround?

Calling System.setProperty("jdk.lang.Process.allowAmbiguousCommands", "true") before the calls to directories-jvm seems to fix the issue \o/

[mnn]

After some stumbling I managed to build the master and the null path issue seems to be fixed. Unfortunately we (I am helping a friend with Windows) only got one step further. Project looks to be created (directory structure, few hs files), but the plugin (or other tool ran by the plugin) has some problem with running the compiler.

Interestingly, the binary file exists and looks fine (as in returns expected output when run with --version). I noticed the error message states a file extension as upper case, but in Total Commander it was in lower case. It shouldn't matter on Windows, unless something is expecting fs to be case-sensitive.

Any ideas what to try next?

Maybe this issue helps #450
