标签： java android build.gradle circleci

我已经花了一天时间在Android项目中使用CircleCI而且我一直在 java.lang.UnsupportedClassVersionError：com / android / build / gradle / AppPlugin：不支持的major.minor版本52.0 当CircleCI运行gradle dependencies命令时。这是一个它显示的堆栈跟踪：

* Where:
Build file '/home/ubuntu/MyProject/app/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':app'.
> java.lang.UnsupportedClassVersionError: com/android/build/gradle/AppPlugin : Unsupported major.minor version 52.0

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
org.gradle.api.GradleScriptException: A problem occurred evaluating project ':app'.

我将build.gradle中的java compileOptions设置为1.7版并启用数据绑定。

android {
...
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}

以前有人遇到过这个问题吗？请给我一些建议。 感谢。

2 个答案:

答案 0 :(得分：14)

您收到此错误是因为 Java 7 VM尝试加载为 Java 8

编译的类

Java 8 的类文件版本为52.0，但 Java 7 VM只能加载最高版本为51.0的类文件

在您的情况下，Java 7 VM是您的gradle构建，类是com.android.build.gradle.AppPlugin

  

请给我一些建议。

尝试更新配置.yml以使用 Java 8 VM：

machine:
  java:
    version: openjdk8 # This line is what you need.
  environment:
    ANDROID_HOME: /usr/local/android-sdk-linux

答案 1 :(得分：1)

我也遇到了同样的情况，因为我没有使用JDK 8 的奴隶填写'限制此项目可以运行的地方'。

确保您选择的从站具有JDK 8.
对我来说它有所帮助。
