run gradle generateProto failed in intellij

[Lin-Liang]

hey guys, I am trying to use gralde generateProtol to generate grpc kotlin code in intellij and it has been unsuccessful. the error message as below:

Caching disabled for task ':generateProto' because: Build cache is disabled Task ':generateProto' is not up-to-date because: Task has failed previously.

• What went wrong: Execution failed for task ':generateProto'.

protoc: stdout: . stderr: Error: Invalid or corrupt jarfile /usr/local/bin/gradle --grpckt_out: protoc-gen-grpckt: Plugin failed with status code 1.

I don't know what happened, the weird thing is that it is ok to run in the terminal。It seems that the two of them are incompatible. And I can successfully generate grpc java code in Intellij, which does not seem to be a problem with Intellij

my environment configuration：

os.detected.name=osx os.detected.arch=x86_64 os.detected.version=10.15 os.detected.version.major=10 os.detected.version.minor=15 os.detected.classifier=osx-x86_64

intellij idea 2019.3.4 (ultimate Edition)

[jamesward]

So you are running the task from the Gradle tasks menu in IntelliJ? What happens if you run the task instead from the command line?

yes, i run Gradle tasks menu in Intellij, if i run the task in terminal command line, every thing is ok.

[jamesward]

I think this is likely because the env vars that are used when running a task from IntelliJ differ from those in a shell. So the PATH and JAVA_HOME are likely different. Unfortunately it seems hard in IntelliJ to change these env vars. Can you check the env vars from when your gradle build runs and see how they differ?

thinks your advice, i had checked look likes the env vars are same. i try to run with --stacktrace and get the following messages

Can you try again with 0.2.0 and the new jar-based artifact: https://github.com/grpc/grpc-kotlin/blob/master/examples/build.gradle.kts#L47

And make sure you bump the com.google.protobufplugin to 0.8.13: https://github.com/grpc/grpc-kotlin/blob/master/examples/build.gradle.kts#L16

[arncore]

@jamesward The jar based artifact doesn't work for me. I had to fallback to 0.1.5 where linux specific binaries were provided. Is there some setup I have to do to run the jar based generator?

            grpckt {

This is from using the IntelliJ. I haven't tested with commandline as I don't have gradle installed (Intellij provides it)

[arncore]

My issue was fixed by updating to latest version of com.google.protobuf:protobuf-gradle-plugin.

[debop]

I use protobuf gradle plugin (0.8.13) (latest), but not work for me in gradle build

[jamesward]

@debop Make sure you specify the plugin artifact like:

artifact = "io.grpc:protoc-gen-grpc-kotlin:0.2.0:jdk7@jar"

[debop]

@jamesward Thanks your solution. It's work.

use

1. com.google.protobuf plugin 0.8.13
2. io.grpc:protoc-gen-grpc-kotlin:0.2.0:jdk7@jar

[asarkar]

I ran into this problem today, and @debop solution worked for me, except I'm using the latest protobuf plugin. Is this documented somewhere where it can be more easily found than looking through closed tickets?

[jamesward]

I think we do need better docs around this, but yeah, it is documented in a non-obvious place: https://github.com/grpc/grpc-kotlin/tree/master/compiler

[keith-miller]

My issue was fixed by updating to latest version of com.google.protobuf:protobuf-gradle-plugin.

Came here from a Google search, this fixed it for me as well.
