Hello,
I am creating a snap. The application is written in Kotlin and we use Bazel to build it.
I managed to build the application using the following snapcraft.yaml. However, after building it and install, I cannot run it. It told me that there is no java available.
I did include openjdk-11-jdk in stage-packages, but it does not work. Even if I use snap run --shell preses.perses and type java, it still shows there is no java.
I have struggled in this for a few days. Any help is appreciated.

Perses is a language-agnostic program reducer to minimize a program with respect to a set of constraints. It takes as input a program to reduce, and a test script which specifies the constraints. It outputs a minimized program which still satisfies the constraints specified in the test script. Compared to Delta Debugging and Hierarchical Delta Debugging, Perses leverages the syntax information in the Antlr grammar, and prunes the search space by avoiding generating syntactically invalid programs.

BTW, I tried ``java -jar perses_deploy.jar’’ and it does not work. That’s the reason I include a start.sh for debugging.
