how to pass -Djava.library.path=... to quarkus dev

[kurtseebauer]

Hi all,

I need to start my application with a native library, using the -Djava.library.path parameter. the java -jar direct start works fine, but I also want to start the dev server with gradle. quarkus dev or quarkus dev -Djava.library.path=... leads to

Caused by: java.lang.UnsatisfiedLinkError: no getdrgjni in java.library.path: /usr/java/packages/lib:/usr/lib64:/lib64:/lib:/usr/lib

Is there any way I could make the dev server aware of my library?

Thank you!

I think you have to configure this option in the quarkusDev task in your build.gradle(.kts).

The order of the properties on the command line is also relevant for the gradle cli (https://docs.gradle.org/current/userguide/command_line_interface.html). I am not sure if this is also true for system properties.

You could try gradlew -Djava.library.path=... quarkusDev instead of gradlew quarkusDev -Djava.library.path=....

I think it won't work either but you can give it a try. 😄

Hi @mschorsch , thanks for the pointer. For some reason passing the argument to gradlew quarkusDev does not work for java.library.path as it does for other arguments, also there is no equivalent env variable like JAVA_LIBRARY_PATH.

But, setting LD_LIBRARY_PATH to include my binary library seems to do the trick.
For future reference:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my/binary/libraries quarkus dev
