Running KSP from command line

KSP is a Kotlin compiler plugin and needs to run with Kotlin compiler. Download and extract them.

#!/bin/bash

# Kotlin compiler
wget https://github.com/JetBrains/kotlin/releases/download/v2.0.21/kotlin-compiler-2.0.21.zip
unzip kotlin-compiler-2.0.21.zip

# KSP
wget https://github.com/google/ksp/releases/download/2.0.21-1.0.25/artifacts.zip
unzip artifacts.zip

To run KSP with kotlinc, pass the -Xplugin option to kotlinc.

-Xplugin=/path/to/symbol-processing-cmdline-2.0.21-1.0.25.jar

This is different from the symbol-processing-2.0.21-1.0.25.jar, which is designed to be used with kotlin-compiler-embeddable when running with Gradle. The command line kotlinc needs symbol-processing-cmdline-2.0.21-1.0.25.jar.

You'll also need the API jar.

-Xplugin=/path/to/symbol-processing-api-2.0.21-1.0.25.jar

See the complete example:

#!/bin/bash

KSP_PLUGIN_ID=com.google.devtools.ksp.symbol-processing
KSP_PLUGIN_OPT=plugin:$KSP_PLUGIN_ID

KSP_PLUGIN_JAR=./com/google/devtools/ksp/symbol-processing-cmdline/2.0.21-1.0.25/symbol-processing-cmdline-2.0.21-1.0.25.jar
KSP_API_JAR=./com/google/devtools/ksp/symbol-processing-api/2.0.21-1.0.25/symbol-processing-api-2.0.21-1.0.25.jar
KOTLINC=./kotlinc/bin/kotlinc

AP=/path/to/your-processor.jar

mkdir out
