问题

运行 weex build android 命令时出现如下错误：

BUILD FAILED in 2s
    
        at checkExecSyncError (child_process.js:601:13)
        at Object.execSync (child_process.js:641:13)

    FAILURE: Build failed with an exception.
    
    * What went wrong:
    Execution failed for task ':app:javaPreCompileRelease'.
    > Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration.
        - weexplugin-processor-1.3.jar (com.taobao.android:weexplugin-processor:1.3)
      Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.
      See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.
    
    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

原因

工程依赖了 weexplugin-processor 的 jar 包，而 jar 包里面用到了注解。在新的 gradle 版本里，需要写新的 groovy 代码来对每个引用注解的地方单独配置。

解决办法

1.在 platforms\\android\\app\\build.gradle 文件中，使用 javaCompileOptions

defaultConfig {
            applicationId "com.weex.app"
            minSdkVersion project.appMinSdkVersion
            targetSdkVersion project.targetSdkVersion
            versionCode 1
            versionName "1.0.0"
            ndk {
                abiFilters "x86"
                abiFilters "armeabi"
            }
            //添加了javaCompileOptions 
            javaCompileOptions {
                annotationProcessorOptions {
                    includeCompileClasspath true
                }
            }
        }

2.在 platforms\\android\\app\\build.gradle 文件中，使用 annotationProcessor

dependencies {
        compile fileTree(include: ['*.jar'], dir: 'libs')
        compile 'com.taobao.android:weex_sdk:0.16.0'
        compile 'com.google.code.findbugs:jsr305:2.0.1'
        compile 'com.squareup.okhttp:okhttp:2.3.0'
        compile 'com.squareup.okhttp:okhttp-ws:2.3.0'
        compile 'com.squareup.okio:okio:1.0.1'
        compile 'com.squareup.picasso:picasso:2.5.2'
        compile "com.alibaba:fastjson:${project.fastjsonLibVersion}"
        compile "com.android.support:support-v4:${project.supportLibVersion}"
        compile "com.android.support:appcompat-v7:${project.supportLibVersion}"
        compile "com.android.support:design:${project.supportLibVersion}"
        compile "com.android.support:support-annotations:${project.supportLibVersion}"
        compile 'com.taobao.android:weex_inspector:0.10.0.5'
        compile 'com.journeyapps:zxing-android-embedded:3.4.0'
        // PLUGIN GRADLE EXTENSIONS START
        compile 'com.taobao.android:weexplugin-loader:1.3'
    
    
        compile 'com.taobao.android:weexplugin-processor:1.3'
        //添加了annotationProcessor
        annotationProcessor 'com.taobao.android:weexplugin-processor:1.3'
    
    
        compile 'com.taobao.android:weexplugin-annotation:1.3'
        // PLUGIN GRADLE EXTENSIONS END
    }

此时出现如下错误：

从问题中可以发现，此时无法加载 com.alibaba:fastjson:1.1.27-android 依赖。下载依赖（[网址][Link 1]），然后将其放在 C:\\Users\\feng.m2\\repository\\com\\alibaba\\fastjson\\1.1.27-android 目录下即可，如图

推荐使用方案2，因为错误提示中，说明 javaCompileOptions 方法之后可能被删除！
