Question

我有一个实用程序项目，让我们调用它utility-library，其中包含一个具有以下结构的类。

public interface OuterInterfaceI {

    public static class InnerClass {
        // ... a couple of static and non static methods
    }

}

现在，当我尝试在utility-library内执行以下操作时，它编译得很好

OuterInterfaceI.InnerClass innerClassObject;

现在我需要在另一个项目中使用它，所以我将项目的jar utility-library.jar（通过mavent构建）添加到我的项目的构建路径（让我们称之为my-application）。当我尝试在类中编写以下代码时，它无法编译。

import com.utility.commons.OuterInterfaceI;

public class SomeClass {
    private static OuterInterfaceI.InnerClass myObject;
}

编译器失败并显示以下错误消息

The type com.utility.commons.OuterInterfaceI.InnerClass cannot be resolved. It is indirectly referenced from required .class files.

我确保utility-library.jar在类路径上。我缺少什么？

更新

我正在使用Eclipse Version：Mars.1 Release（4.5.1）和maven 3.3.3 with java 1.8.0_45。我认为这可能是eclipse中的一个错误，但是当我尝试从终端构建时，我遇到同一个类的编译时间问题
