makefile exit 2 even it the build succeed

[eoli3n]

The build succeed, but exit code is not 0.
aur PKGBUILD noticed that too -> https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=libdecsync#n17

Please check https://github.com/void-linux/void-packages/runs/4649345169?check_suite_focus=true

I don't know why it happens. From the log it looks like some parts are executed twice for some reason. See

./gradlew linkReleaseSharedlinuxX64
./gradlew linkReleaseSharedlinuxX64
Makefile:38: *** open: build/bin/linuxX64/releaseShared/decsync.pc: No such file or directory.  Stop.
make: *** Waiting for unfinished jobs....

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.

But it only happens on clean (?) builds, if I try it myself it works fine.

The reason it exits with 2 is that it tries to use decsync.pc (for what?) before it is created.

The current Makefile doesn't support -j option. You should disable build parallelization.
