Question

我已从Eclipse Indigo切换到ADT（版本22.3.0）我通过命令行使用Maven编译项目：

mvn clean install android:deploy android:run

该项目在我的旧系统上编译良好，我根本没有改变它。现在，当我将其导入ADT时，我在编译期间收到“已添加”错误：

...

我没有在此问题的其他回复中看到的X_src文件。我的lib文件夹中也没有包含任何库即使使用基本的POM文件也会发生这种情况，所以我猜ADT已经以某种方式更改了项目，所以它包括这个LineTokenizer两次（我不包括它在哪里），这是正确的吗？有谁知道如何解决这个问题，或者找到多个包含物发生的位置？

如果ADT找到同一个包但具有不同版本号的多个实例，则会抛出该错误。查看您的pom中的一个依赖项是添加与编译器提供的LineTokenizer不同的<exclusions>。我建议你使用maven POM编辑器转到依赖层次结构。这将允许您选择无关的依赖关系，然后可以通过右键单击并选择“Exclude Maven Artifact ...”来排除该关联，这将自动向您的POM添加mvn clean install元素。这将从Eclipse类路径中删除重复的JAR，并允许您构建项目。完成编辑POM后执行{{1}}。
