java – 添加jar文件后的Android Studio preDexDebug

我有一个自己的框架,我用于课堂上的任务(学校课程,而不是Java类),我把它变成了一个.jar文件,这样每当我对框架进行更改时,我都可以拖放它进入Android Studio.在过去的5个左右的类任务中,一切都运行良好,现在突然间,在点击运行后解析我的.jar时,我得到了一个preDexDebug失败错误.我在一个空白项目上测试了这个.该项目共有2个.jars：Gson和我自己的jar.在我拉入我自己的.jar之后,它打印出preDexDebug失败…我已经在这两个真正的时间里挣扎了,我不知道我能做些什么来解决这个问题…

我已经尝试重建,清理,检查gradle.build是否有重复项,多次复制项目,以及多次编译和复制.jar.

Ubuntu x64与64位Oracle JDK 1.8.0_31.使用与JDK捆绑在一起的Java
