  • The type javax.ws.rs.core.MediaType cannot be resolved. It is indirectly referenced from required .class files

    看到了http://stackoverflow.com/questions/5547162/eclipse-error-indirectly-referenced-from-required-class-files , 也没搞明白。 后面被证明, 实际上还是Unresolved compilation problems

    开始总还以为是缺少jar 呢, 但是jar 明明就是 lib 目录中的啊。。。 重启数次都不行,

    后面 看到 Unresolved compilation problems, 突然,想到, 可能是编译的问题吧。。

    找到AttachmentRestService, 反编译看看, 果然, 各个方法都是错误:
