调试build.gradle文件

Question

windows powershell中的建筑。已经尝试过java version 8和gradle更新

./gradlew build.gradle对使用Java7运行Gradle的支持已被废弃，并计划在Gradle 5.0中删除。有关更多细节，请参见compilation。

失败:生成失败，异常。

• 其中:构建文件'C:\ProjectChaayos\KettleAndroid\assembly\build.gradle‘行: 10
• 哪里出了问题:一个评估项目‘：组装’的问题发生了。 java.lang.UnsupportedClassVersionError: com/android/build/gradle/AppPlugin :不支持的major.minor版本52.0
• 尝试:使用--stacktrace选项运行以获得堆栈跟踪。使用--info或-调试选项运行以获得更多日志输出。用扫描来获得完整的洞察力。

下面是控制台中显示错误的build.gradle文件，即

如您所见，在第10行抛出错误。

:apply plugin'com.android.application'

等级-包装。属性：-

看起来你并没有在build.gradle文件中引用gradle

我希望看到下面列出的依赖项

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

使用适当的gradle版本
