I am using IntelliJ (not sure if it matters). How can I add java compiler parameter to "runClient" configuration and "build" gradle task? I want to add harmless "-parameters" flag, so class files inside jar will contain original parameter names.

If you are talking about the parameters in vanilla classes, this will not work.

Forge use decompiled vanilla code which was obfuscated by mojang, all parameter, field, method and class names have some wierd names like A.a or HB.c.
Forge is be able to load the original field, method and class names from the decompiled code, if i remember correctly the parameter names are not complied means Forge can not load them.

if you wish parameter names and javadocs you can take a look at: https://github.com/ParchmentMC/Parchment/wiki

Thanks, but I don't need parameter in vanilla classes, I need parameters in my own mod classes.

The reason for this I developed simple scripting language I integrated in my mod, and I want to automatically build API reference by using reflection over API classes. Parameter names can be good to understand what method is doing.

Something like the following in your build.gradle

Quote

tasks.withType(JavaCompile).configureEach {
    it.options.compilerArgs.add("-parameters")
}

I haven't tested the above, so if it doesn't work, check the gradle and javac docs for the exact magic incantation. 🙂

You will probably need to delete the build/classes folder to force gradle to do recompile everything.

Thanks, works like a charm!
