【问题描述】：

我在 android studio 中构建 groovy 代码时出错。 错误消息是

C:\Users\Administrator\Desktop\lytest110\app\src\main\java\gzzhe\com\lytest110\MainActivity.java:41: error: can't find symbol
        Log.d("lytest110", GroovyTest.getMsg());
                           ^
  symbol:   parameter GroovyTest
  possition: class MainActivity
1 error

 FAILED
:app:compileDebugGroovy

FAILURE: Build failed with an exception.

我的 build.gradle 是：

buildscript 
    repositories 
        jcenter()
    
    dependencies 
        classpath 'com.android.tools.build:gradle:0.13.2'
        classpath 'me.champeau.gradle:gradle-groovy-android-plugin:0.3.4'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    


allprojects 
    repositories 
        jcenter()
    

app目录下的build.gradle：

    apply plugin: 'com.android.application'
apply plugin: 'me.champeau.gradle.groovy-android'
android 
    compileSdkVersion 19
    buildToolsVersion "19.1.0"

    defaultConfig 
        applicationId "gzzhe.com.lytest110"
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    
    buildTypes 
        release 
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        
    


dependencies 
    compile files('libs/groovy-2.4.0-beta-3-grooid.jar')
    compile files('libs/android-support-v4.jar')
    compile fileTree(include: ['*.jar'], dir: 'libs')
    //    compile 'com.android.support:support-v4:19.+'

我已将 groovy 文件放入 main/groovy/package/name 目录。 groovy 使用@CompileStatic 进行注释。

这个问题困扰了我好几天。

【参考方案1】：

从您的错误来看，您似乎正在使用 Java 调用 Groovy 类。根据 Android Groovy 插件自述文件。它说

Groovy sources must be found inside src/main/groovy. Note that the plugin follows the behavior of the Groovy plugin in Gradle, which means that if you want to be able to have Groovy classes referencing Java classes that themselves reference Groovy classes, then those Java classes must be found inside src/main/groovy too (this is called joint compilation).

所以你只需将 MainActivity.java 放到你的 ../main/groovy/package/name 目录中
