Question

我正在将一个简单的Android应用程序转换为Maven，而且我遇到了第三方jar（ActiveAndroid），其中包含我在我的代码中使用的注释类。我已经确认jar确实包含了注释类文件，当我将它包含在libs目录中时，jar工作正常，并使用Eclipse进行编译。

这是我的POM.xml：

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

这是我的编译错误：

我刚开始使用Maven并在Eclipse之外编译Android应用程序，所以我确信我错过了一些简单的东西。任何朝着正确方向的推动都非常感激！

谢谢！

Answer 1

看起来Maven Central Repo中没有活动的android工件（参见this search）。您可以在自己的本地存储库中安装该jar（使用mvn install-file，但这只能在您的本地计算机上运行。或者您可以将该工件部署到您控制并在POM中引用它的存储库。

Answer 2

你正在使用LATEST。你有可能拥有该工件的多个版本，而Maven正在从Eclipse获得另一个版本吗？

Answer 3

您是否考虑过课程版本问题？只是推测，但可能是jar使用1.6 JDK（目标1.6）构建你的POM已经指定源和目标为1.5，考虑到你也使用1.5 JDK，编译器可能根本无法读取jar文件中的类用1.6编译

Maven找不到外部jar的注释
