Android构建流程——篇三_main manifest missing for variant release.-优快云博客

本文链接：https://blog.youkuaiyun.com/dbs1215/article/details/106967018

这篇博客详细介绍了Android构建过程中四个关键任务：checkDebugManifest、generateDebugBuildConfig、prepareLintJar和mainApkListPersistenceDebug。内容包括每个任务的输入/输出、核心类及其功能，如清单文件校验、BuildConfig.java生成、lint.jar复制规则以及apk信息的gson文件生成。此外，还提到了自定义lint规则的相关资源链接。

Task5 checkDebugManifest

1. input/ouput

taskName:checkDebugManifest
=========================================================
output:/Users/apple/work/project/AndroidGradleTaskDemo/app/build/intermediates/check-manifest/debug

2. 核心类(CheckManifest)

@TaskAction
void check() {
   
    if (!isOptional && manifest != null && !manifest.isFile()) {
   
        throw new IllegalArgumentException(
                String.format(
                        "Main Manifest missing for variant %1$s. Expected path: %2$s",
                        getVariantName(), getManifest().getAbsolutePath()));
    }
}

该任务是校验操作，就是校验清单文件的合法性，不合法则中断任务，抛出异常

配置阶段操作

@Override
public void execute(@NonNull CheckManifest checkManifestTask) {
   
	//1. 设置任务实现类
    scope.getTaskContainer().setCheckManifestTask(checkManifestTask);
	
	//2. 设置相关入参
    checkManifestTask.setVariantName(
            scope.getVariantData().getVariantConfiguration().getFullName());
    checkManifestTask.setOptional(isManifestOptional);
    checkManifestTask.manifest =
            scope.getVariantData().getVariantConfiguration().getMainManifest();
	
	//3. 出参目录配置
    checkManifestTask.fakeOutputDir =
            new File(
                    scope.getGlobalScope().getIntermediatesDir(),
                    "check-manifest/" + scope.getVariantConfiguration().getDirName());
}

依赖任务:preBuildTask

Task6 generateDebugBuildConfig

BuildConfig.java想必大家非常熟悉，该任务就是生成它

1. input/output

taskName:generateDebugBuildConfig
=========================================================
output:/Users/apple/work/project/AndroidGradleTaskDemo/app/build/generated/source/buildConfig/debug
========================END==============================

2. 核心类(GenerateBuildConfig)

@TaskAction
void generate() throws IOException {
   
		
	  //1. 清理操作	
      // must clear the folder in case the packagename changed, otherwise,
      // there'll be two classes.
      File destinationDir = getSourceOutputDir();
      FileUtils.cleanOutputDir(destinationDir);
		
	  //2. 构建一个BuildConfig生成器，用于生成BuildConfig.java	
      BuildConfigGenerator generator = new BuildConfigGenerator(
              getSourceOutputDir(),
              getBuildConfigPackageName());
