Contains: Failed to get bundleInfo for bundle from /home/user/.local/share/nvim/mason/packages/java-test/extension/server/jacocoagent.jar

The problem is that the configuration adds all vscode-java-test JARs as bundles, but some of them are not OSGi bundles:

• com.microsoft.java.test.runner-jar-with-dependencies.jar
• jacocoagent.jar

These files don't contain bundle information in the META-INF/MANIFEST.MF file.

eclipse.jdt.ls tries to access the missing Bundle-Version property:
https://github.com/eclipse-jdtls/eclipse.jdt.ls/blob/master/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/handlers/BundleUtils.java#L335

and throws an exception:
https://github.com/eclipse-jdtls/eclipse.jdt.ls/blob/master/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/handlers/BundleUtils.java#L175

Solution

Exclude the listed JARs from the bundle list.

I "glued" together (temporary?) automated bundle filtering for wildcard bundles loading while dealing with same issue. If anyone finds it useful feel free to use it.

        -- Your bundles collection
        local bundles = vim.split(vim.fn.glob(mason_path .. "packages/java-*/extension/server/*.jar", 1),
            '\n')
        -- Paste it after bundles but before assigning bundles to jdtls
        -- Following filters out unwanted bundles
        local ignored_bundles = { "com.microsoft.java.test.runner-jar-with-dependencies.jar", "jacocoagent.jar" }
        local find = string.find
        local function should_ignore_bundle(bundle)
            for _, ignored in ipairs(ignored_bundles) do
                if find(bundle, ignored, 1, true) then
                    return true
                end
            end
        end
        bundles = vim.tbl_filter(function(bundle) return bundle ~= "" and not should_ignore_bundle(bundle) end, bundles)

I'm sure there is better way but this seems to work good enough for now.
