AnnotationProcessor 调试

[bingoogolapple]

• 在项目根目录下的 gradle.properties 文件中加入如下两条语句

  org.gradle.jvmargs=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
  org.gradle.parallel=true

• 点击 Edit Configurations 配置 Remote，直接点击确认用默认配置就行，注意 address 与 gradle.properties 中的 address 保持一致
• 点击运行 remote
• 给注解处理器项目打上断点，然后 Build->Rebuild Project

生成模块文件

private void generateModuleFile(Filer filer, String fileName) {
    try {
        FileObject fileObject = filer.createResource(StandardLocation.CLASS_OUTPUT, "assets", fileName);
        String tempFilePath = fileObject.getName();
        String schemaFilePath = tempFilePath.substring(0, tempFilePath.indexOf("build/intermediates/classes")) + fileName;
        FileUtils.writeStringToFile(new File(schemaFilePath), "", StandardCharsets.UTF_8);
    } catch (Exception e) {
        e.printStackTrace();
        throw new RuntimeException(String.format(">>> 生成文件 %s 失败 %s", fileName, e.getMessage()));
    }
}

通过 assets 文件来区分模块

/**
 * 将模块名称信息写到
 * 1.「模块/build/intermediates/classes/debug/assets/xxxx/」目录下
 * 2.「aar 解压后目录/classes.jar 解压后目录/assets/xxxx/」目录下
 *
 * 存在多个同名文件时会中断编译
 *
 * Android 中通过 AssetManager assetManager = mApplication.getResources().getAssets();
 * String[] list = assetManager.list('xxxx'); 来获取

        FileObject fileObject = filer.createResource(StandardLocation.CLASS_OUTPUT, "", path);

        writer = fileObject.openWriter();
