Need help on using Kapt with the cli

EDIT: fixed first version, now I have a different problem :slight_smile:

Hi, I’m trying to make the kotlin annotation processor work from the command line kotlinc.
I have a small example here https://github.com/sky87/kapt-cli-example

What I’m doing right now is this (build.sh)

#!/usr/bin/env bash

if [ -z "$KOTLIN_HOME" ]; then
  KOTLIN_HOME=kotlinc
  PATH=$KOTLIN_HOME/bin:$PATH
fi

CLASSPATH=lib/org.mapstruct-mapstruct-1.2.0.Final.jar:lib/org.mapstruct-mapstruct-jdk8-1.2.0.Final.jar:build/classes
KT_DEPS=$KOTLIN_HOME/lib/kotlin-runtime.jar:$KOTLIN_HOME/lib/kotlin-stdlib-jdk8.jar:$KOTLIN_HOME/lib/kotlin-reflect.jar


rm -rf build
mkdir -p \
  build/classes \
  build/kapt/sources \
  build/kapt/classes \
  build/kapt/stubs

kotlinc \
  -cp  $CLASSPATH \
  -d build/classes \
  -Xplugin=$KOTLIN_HOME/lib/kotlin-annotation-processing.jar \
    -P plugin:org.jetbrains.kotlin.kapt3:sources=build/kapt/sources \
    -P plugin:org.jetbrains.kotlin.kapt3:classes=build/kapt/classes \
    -P plugin:org.jetbrains.kotlin.kapt3:stubs=build/kapt/stubs \
    -P plugin:org.jetbrains.kotlin.kapt3:apclasspath=lib/org.mapstruct-mapstruct-processor-1.2.0.Final.jar \
    -P plugin:org.jetbrains.kotlin.kapt3:processors=org.mapstruct.ap.MappingProcessor \
    -P plugin:org.jetbrains.kotlin.kapt3:aptMode=stubsAndApt \
    -P plugin:org.jetbrains.kotlin.kapt3:verbose=1 \
  src

java \
  -cp $KT_DEPS:$CLASSPATH \
  MainKt

When I run this I get

error: [kapt] 'com.sun.tools.javac.util.Context' class can't be found ('tools.jar' is absent in the plugin classpath). Kapt won't work.

even though

> ls $JAVA_HOME/lib | grep tools
tools.jar

any idea?

Thanks,
Fra

Hello, does it help to apply the suggestion from this comment?

Even if it does solve the problem I think it’s worth it to create a YouTrack issue, if only for documentation purposes.

I solved the problem by adding tools.jar to the cp in the shell script that invokes the compiler, this is a much cleaner solution though :slight_smile:
