Question

我有一系列相互依赖的GWT项目，所有链编译都很好，但最后一个元素似乎无法从生成的依赖jar中读取java类：

我在错误中检查了jar，.java和.class文件确实存在于它们应该是的位置：编译器找到包含所需类的jar

令人惊讶

ShopAdmin-1.0.jar

但它没有读过它（许多类都是这种情况，请参阅 the compilation output）

 [ERROR] Errors in 'jar:file:/C:/Users/Zied%20Hamdi/git/VuMe/ShopAdmin/build/libs/ShopAdmin-1.0.jar!/fr/onevu/vume/shopadmin/ShopAdmin.java'
            [ERROR] fr.onevu.vume.shopadmin.ShopAdminClientFactory cannot be resolved to a type

你可以看到

ShopAdminClientFactory.java与ShopAdmin.java位于同一个包中

此外，项目Customer（正在编译）不包含ShopAdmin.java，此文件位于依赖项目中（Customer依赖于所有其他项目）。奇怪的是，在编译客户时，错误是关于一个不在客户中的类，而是与其直接相关的ShopAdmin（客户始终是商店管理员）。

但是生成的jar文件包含了所有内容：uncompresses jar包含应该在那里的类：

有什么想法吗？

确定！

这是我的错，我没有必要手动解决依赖关系一段时间。这只是一个类路径问题（手动添加一个jar，因为它在maven上不可用）

我只需要遵循未解析的符号原因链，直到找到对// https://mvnrepository.com/artifact/com.google.gwt.google-apis/gwt-ajaxloader的依赖关系编译组：'com.google.gwt.google-apis'，名称：'gwt-ajaxloader'，版本：'1.1.0'未添加
