java - 将 POI 与 gradle 一起使用时出现重复输入错误

Question

我开始了一个需要 Apache POI 库的项目。我将它们粘贴到我的 build.gradle 文件中，一切似乎都很好。直到我构建调试应用程序。

我收到以下错误:

Error:Execution failed for task ':mobile:transformClassesWithJarMergingForDebug'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/apache/xmlbeans/xml/stream/Location.class

我尝试删除和添加排除组和模块，但没有任何帮助。当我确实获得调试 apk 以构建并运行应用程序时，应用程序崩溃，因为在打开 DOCX 文件时找不到 org.apache.xmlbeans.XmlOptions。 DOC 文件工作正常。

这是我的 build.gradle 文件:

        // set to true to turn off analysis progress reporting by lint
        quiet false
        // if true, stop the gradle build if errors are found

我已经检查过是否有任何其他依赖项使用 org.apache.xmlbeans 依赖项，但我没有找到。

如果有人有解决方案，请随时回答问题，但如果您告诉我们您是如何得出答案的，我将不胜感激。

编辑:

执行这条命令时:

gradlew -q dependencies mobile:dependencies --configuration compile

(此处输出:http://pastebin.com/7TugFR3J) org.apache.xmlbeans 依赖项只列出一次。是否存在与任何默认 Java 组件相关的问题？

编辑 2:

我发现Java有这样一个组件:javax/xml/stream/Location.class 所以我想我需要从构建中删除它，但我不知道如何。

Answer 1

你可以尝试这样的事情。

1. 解压缩jar 文件。 (只需将 .jar 扩展名更改为 .zip
2. 这将删除重复的文件。
3. 使用 jar cf xmlbeans.jar -C(解压缩文件夹的路径)重新创建 jar。(注意，命令末尾有一个点)
4. 使用这个重新生成的jar
