android gradle 增量 lint

Question

因为我会做 Android 的增量 Lint 检查，我看了一些文章，我发现我可以在 build.gradle 中添加一个任务，然后通过重写 LintGradleClient 来传递一些参数，它应该按照这篇文章，但是我按照文章描述的，在增加LintGradle参数AndroidProject cannot be got，我用kotlin实现的地方。谁能帮帮我？这里是文章url路径https://www.jianshu.com/p/4833a79e9396

我在 get AndroidProject as Kotlin 中的代码:

fun getAndroidProject(): AndroidProject{
   var gradleConn = GradleConnector.newConnector()
   gradleConn.forProjectDirectory(getProject().getProjectDir())  
   var modelProject =   gradleConn.connect().getModel(com.android.builder.model.AndroidProject::class.java)
   return modelProject
}

然后我运行任务，它告诉我这样:

No model of type 'AndroidProject' is available in this build.

那篇文章的android插件版本是旧的，从3.0.0开始获取AndroidProject的方式已经改变了。

看完gradle android plugin的源码后，com.android.build.gradle.tasks.LintBaseTask给出了一个线索:

protected AndroidProject createAndroidProject(Project gradleProject) {
    String modelName = AndroidProject.class.getName();
    ToolingModelBuilder modelBuilder = this.toolingRegistry.getBuilder(modelName);

    assert modelBuilder != null;

    ExtraPropertiesExtension ext = gradleProject.getExtensions().getExtraProperties();
    ext.set("android.injected.build.model.only.versioned", Integer.toString(3));
    ext.set("android.injected.build.model.disable.src.download", Boolean.valueOf(true));

    AndroidProject var5;
    try {
        var5 = (AndroidProject)modelBuilder.buildAll(modelName, gradleProject);
    } finally {
        ext.set("android.injected.build.model.only.versioned", (Object)null);
        ext.set("android.injected.build.model.disable.src.download", (Object)null);
    }

    return var5;
}

继续追踪，我们可以发现:
1. toolingRegistry 由GlobalScope.getToolingRegistry()
获取2. GlobalScope 由VariantScope.getGlobalScope()
获取3. VariantScope由ApplicationVariant.getVariantData().getScope()

获取

ApplicationVariant是com.android.application插件中applicationVariants的元素，可以遍历applicationVariants 列出来获取它。

这是app/build.gradle中的示例代码:

android {
    // other script...

    applicationVariants.all { variant ->
        def globalScope = variant.variantData.scope.globalScope
        String modelName = AndroidProject.class.getName()
        ToolingModelBuilder modelBuilder = globalScope.toolingRegistry.getBuilder(modelName)
        AndroidProject androidProject = (AndroidProject) modelBuilder.buildAll(modelName, project)
        // create your task to do something
    }
}
