How to get the path for shared articafacts of a package?

[s1n7ax]

There are API like registry.get_pkg_path and package:get_install_path however I couldn't find an API to get the path to shared artifacts.

My requirement is to get .jars from java-test package instead of looking for .jars inside installed path.

Reaching into the internal package structure is not recommended and not supported as this may change in-between versions. Instead, these artifacts are also available at a stable location inside the bin/ (executables), share/ (architecture-independent files), and opt/ (rarely used for architecture-dependent files) directories. .jar files will be found inside the share/ directory. The recommended way to access these are by expanding the $MASON environment variable which mason.nvim sets up during setup.

In the case of java-test, this could for example look like:

local java_test_jar = vim.fn.glob "$MASON/share/java-test/com.microsoft.java.test.plugin-*.jar"
-- /Users/williamboman/.local/share/nvim/mason/share/java-test/com.microsoft.java.test.plugin-0.39.0.jar

-- do something with the file path to the jar…

Note that the above example uses :h glob() which will return the empty string "" if the file doesn't exist (i.e. java-test is not yet installed).
