buildSrc kotlinplugin_0">buildSrc使用kotlin开发plugin配置

配置

apply plugin: 'java-gradle-plugin'
apply plugin: 'kotlin'

buildscript {
    repositories {
        mavenLocal()
        maven {
            url uri("${rootProject.rootDir}/.repo")
        }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
        maven { url 'https://jitpack.io' }
        maven { url 'https://dl.google.com/dl/android/maven2/' }
        google()
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10"
    }
}

Properties props = new Properties()
props.load(project.file('../gradle.properties').newDataInputStream())
def isDebugLintPlugin = props.getProperty('DEBUG_LINT_PLUGIN')
def gradlePluginVersion = props.getProperty('gradlePluginVersion')

println "isDebugLintPlugin ${isDebugLintPlugin} gradlePluginVersion ${gradlePluginVersion}"

repositories {
    mavenLocal()
    maven {
        url uri("${rootProject.rootDir}/.repo")
    }
    maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
    maven { url 'https://jitpack.io' }
    maven { url 'https://dl.google.com/dl/android/maven2/' }
    google()
    mavenCentral()
}

dependencies {
//    //gradle sdk
//    implementation gradleApi()
//    //groovy sdk
//    implementation localGroovy()

    testImplementation 'junit:junit:4.13.2'

    implementation "com.android.tools.build:gradle:${gradlePluginVersion}"

    compileOnly 'com.google.android:android:4.1.1.4'
}

gradlePlugin {
    // Define the plugin
    plugins {
        MyLintPlugin {
            id = 'com.lkl.lint.MyLintPlugin'
            implementationClass = 'com.lkl.android.lint.plugin.MyLintPlugin'
        }
    }
}

sourceSets {
    main {
        if (isDebugLintPlugin) {
            kotlin.srcDirs += "${project.rootDir.parent}/Lint/LintPlugin/src/main/kotlin"
            resources.srcDirs += "${project.rootDir.parent}/Lint/LintPlugin/src/main/resources"
            println "add lintPlugin src"
        }
    }
}

配置的关键点是buildscript的配置，否则会出现如下的相关问题：

遇到的问题

kotlin_not_found_80">Plugin with id ‘kotlin’ not found.

Build file '/Users/likunlun/Android/Projects/AndroidLint/buildSrc/build.gradle' line: 2

A problem occurred evaluating project ':buildSrc'.
> Plugin with id 'kotlin' not found.

我们在其他的module里都是可以正常的found，这个是由于没有引用对应的classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"，但是这个我们在项目根目录下的build.gradle里已经加上了，为啥buildSrc里还是会出现 not found 呢？

我们分别在buildSrc里的build.gradle里加上如下打印：

println(“buildSrc config”)

项目根目录下的build.gradle里加上如下打印：

println(“root config”)

我们执行一下编译指令：

abc:AndroidLint likunlun$ gradlew assemble

> Configure project :buildSrc
buildSrc config
isDebugLintPlugin true gradlePluginVersion 4.1.2
add lintPlugin src

> Configure project :
root config

> Configure project :app

从上面的打印可以看出，buildSrc下的build.gradle优先于根目录下的build.gradle执行。

解决方案，我们在buildSrc里的build.gradle添加如下代码：

buildscript {
    repositories {
        mavenLocal()
        maven {
            url uri("${rootProject.rootDir}/.repo")
        }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
        maven { url 'https://jitpack.io' }
        maven { url 'https://dl.google.com/dl/android/maven2/' }
        google()
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.10"
    }
}
