Android Studio构建错误

Question

我一直试图解决这个问题。我不知道该怎么办，当我想调试项目时，我会卡在下面的输出错误上。

Execution failed for task ':inspectoratecalculator:dexDebug'.

Answer 1

我不确定你是否也有同样的问题，但我的问题是我使用JDK 1.8来编译代码，androiddx工具不支持这一点。

修复方法是在项目的模块设置中将SDK路径从1.8更改为1.7 JDK。

有关Mac中的详细配置，请参考以下内容：https://stackoverflow.com/a/24680375/1043032

Answer 2

这可能是因为在构建项目的过程中多次引用同一个jar，可能是jar已经包含在其他模块或库模块中。再次检查并确保不存在这种情况。

我们之前就遇到过这种问题。

Answer 3

从project/module JAR目录中删除v4 JAR文件，如@rupps所述。同时从配置中删除“排除”部分。因为您使用的是appcompat-v7依赖项，所以您将通过Maven自动获取v4支持库。
