Im having issues with getting stderr or any output really fr kotlinlang #compiler

Im having issues with getting stderr (or any output really) from a compiler plugin being printed on a gradle setup. This is still on the pre-K2 API. The plugin is being invoked and the codepaths that the print statements are on are being executed, so Im a bit lost as to whats going on. Any leads? Im trying to log exceptions in the plugin, but I cant get them to be logged. Not catching the exceptions works fine, but it fails the build which we really dont want to do

The plugin code https://github.com/sourcegraph/lsif-kotlin/pull/55/files the gradle init script and other stuff where it is being added https://sourcegraph.com/github.com/sourcegraph/scip-java/-/blob/scip-java/src/main/s[…]urcegraph/scip_java/buildtools/GradleBuildTool.scala?L199-217

Kotlin compiler is usually running in a separate process, you should use

MessageCollector

to output CLI messages.

Im using that but also not getting anything, [here](https://github.com/sourcegraph/lsif-kotlin/pull/55/files#diff-c45f296394213ffe019fd64975953053f79045256cd96b443a8695803643a036R30-R32) and [here](https://github.com/sourcegraph/lsif-kotlin/pull/55/files#diff-c45f296394213ffe019fd64975953053f79045256cd96b443a8695803643a036R82-R100)

formatting fail :miffed:

With

kotlin.compiler.execution.strategy=in-process

Im able to get see that the message collector fetched with

CompilerConfiguration().get(CLIConfigurationKeys.MESSAGE_COLLECTOR_KEY, MessageCollector.NONE)

returns the

NONE

collector. This isnt gonna be particularly reliable for me if its gonna be set to

NONE

by default

Im able to set

kotlin.compiler.execution.strategy=in-process

and default to

PrintingMessageCollector

instead of

NONE

, so that seems like an ok workaround

That doesn't seem right, but I didn't check this part of the pipeline for awhile :)

The in-process workaround should work fine for debugging only, I think

Its as part of semantic indexing, so its not “critical” realistically, so i think its “fine” for this https://github.com/sourcegraph/scip-java/
