So this is my current build.gradle
file:
/*
* This file was generated by the Gradle 'init' task.
*
* This generated file contains a sample Java Library project to get you started.
* For more details take a look at the Java Libraries chapter in the Gradle
* User Manual available at https://docs.gradle.org/5.6.1/userguide/java_library_plugin.html
*/
apply plugin: 'groovy'
apply plugin: 'java-gradle-plugin'
repositories {
google()
}
dependencies {
compile gradleApi()
}
From everything I've read in the gradle documentation, I believe this is all I should need to actually create a plugin. By that I mean being able to import Plugin from the org.gradle package.
However, org.gradle cannot be found on my build path.
What else do I need to do?
Judging from the comment in the Gradle build you provided, I am assuming you have installed Gradle on your local machine and you used gradle init
to generate what you have now. Except you generated a java-library
build type when you should have generated Gradle plugin build type.
Since you have the groovy
plugin applied, I assume you want a Groovy based Gradle plugin, so simply run gradle init
again, but select groovy-gradle-plugin
plugin type. For example, using Gradle 6.2.2 on my local machine, my terminal output for generating a Gradle plugin project using Groovy shows:
➜ gradle init
Select type of project to generate:
1: basic
2: application
3: library
4: Gradle plugin
Enter selection (default: basic) [1..4] 4
Select implementation language:
1: Groovy
2: Java
3: Kotlin
Enter selection (default: Java) [1..3] 1
Select build script DSL:
1: Groovy
2: Kotlin
Enter selection (default: Groovy) [1..2] 1
Project name (default: example-groovy):
Source package (default: example.groovy):
> Task :init
