Question

我有几个Android库项目，我正在尝试转换为Maven。

我遇到了 mvn clean install 成功的问题但在Eclipse中存在导入问题，好像project2 apklib中的类不在project1的类路径中。

第一个项目POM.xml

技术的：

我正在使用Eclipse Kepler。
我正在使用M2E的最新Android Configurator（取自eclipse市场）

我的问题：

当依赖于apklib时，我们是否应该在Eclipse中看到有关此依赖项的任何证据（如从此库中编译的.class）？
为什么Eclipse无法从依赖的apklib中的包中找到导入？

Answer 1

您必须在Eclipse工作区中导入APKlib，然后将其链接到您的主应用程序项目（项目属性＆gt; Android＆gt;添加库并选择您的APKLib项目）

有时，如果您执行maven项目的清理或更新，Eclipse会丢失apklib的链接，您必须再次添加它。

依赖于外部apklib时Eclipse编译错误
