android - 配置后无法创建变体 'android-lint'

Question

我正在将项目的 Gradle 插件从 2.1.2 更新到 3.1.0，但是 gradle 在构建时开始抛出错误:

Cannot create variant 'android-lint' after configuration ':app:debugRuntimeElements' has been resolved

项目级渐变:

 // Top-level build file 
 buildscript {
repositories {
    jcenter()
    mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
    google()

}
}

 // Used to disable preDex, will speed up clean build but slow down incremental builds.
  project.ext.preDexLibs = !project.hasProperty('disablePreDex')

 subprojects {

    if ("com.android.build.gradle.AppPlugin".equals(plugin.class.name)) {
        project.android.dexOptions.preDexLibraries = rootProject.ext.preDexLibs
    } else if ("com.android.build.gradle.LibraryPlugin".equals(plugin.class.name)) {

我被这个问题困住了，没有找到任何解决方案。谁能帮帮我。

Answer 1

我在另一个图书馆遇到了和你一样的问题。 我可以通过替换这一行来解决这个问题:

classpath = files(variant.javaCompile.classpath.files) + files(ext.androidJar)

与:

doFirst { classpath = files(variant.javaCompile.classpath.files) + files(ext.androidJar) },

“这是由于 AndroidStudio 更新时新的 Gradle 插件与 JavaDoc 插件发生冲突”，如果您有 Javadoc 任务，您必须能够找到相同的行。
