-------------------------------
Summary: Add a conditional expression for profile activation
evaluating to true if a certain executable can be found in the system path
Key: MNG-8768
URL: https://issues.apache.org/jira/browse/MNG-8768
Project: Maven
Issue Type: Sub-task
Reporter: Juan Farré
I have a use case that I think is of general interest.
I am generating a native image with GraalVM native-maven-plugin, and I'd like
to autodetect the presence of the musl gcc compiler wrapper
x86_64-linux-musl-gcc in the path to generate a static executable.
When using GraalVM to build an image with the following options,
{code:bash}
native-image --static --libc=musl ...{code}
it tries to use x86_64-linux-musl-gcc to compile. If it isn't available in the
system path, it crashes.
My idea is to activate a profile when building under Linux x86_64 and the
executable x86_64-linux-musl-gcc is detected in the path. This profile would
add the options --static and --libc=musl to the native-maven-plugin
configuration.
It could be an expression like executable(executable_name_or_path), which would
search for the executable in the system path (unless a path is given) and check
that it's actually an executable.
I think this can be useful for many other use cases.
