I'm trying to build JPostal as described in this link using the following command:

./gradlew assemble

However, the command produces the following output claiming the file C:\x\Program Files\Msys64\usr\share does not exist when it clearly does:

$ ./gradlew assemble

:buildJniLibaclocal-1.16: error: aclocal: file '/x/Program Files/Msys64/usr/share/aclocal/tcl-tea.m4' does not exist

BUILD FAILED

I can clearly see a file named tcl-tea.m4 in the directory: C:\x\Program Files\Msys64\usr\share\aclocal

See the screenshot below:

If the file clearly exists, why am I getting this error? Why is the file being discriminated against?

Despite these are supported, but paths with spaces generally tend to be problematic on Linux.
Even without the build.gradle, the path is obviously wrong; this likely needs to be escaped:

"C:\\x\\Program\ Files\\Msys64\\usr\\share\\aclocal"

Where \\ gives \ and \ gives .

To use ${File.separator} would be the alternate cross-platform approach.

This would give \ on Windows and / on Linux.
