Question

我必须使用EMF项目并且需要使用另一个包中的一些类。当我尝试用maven构建生成的代码时，我得到了这个失败：

[INFO] 6 errors

所有库都已导入并在pom中，但生成的ModelSwitch类仍然存在问题。

这个错误和事实，Eclipse Luna是错误的，因为地狱让我疯了！有人可以帮助我并解释如何解决这个问题吗？

Answer 1

这些是我所知道的组件的最新版本

<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>ecore</artifactId>
    <version>2.3.0-v200706262000</version>
</dependency>
<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>common</artifactId>
    <version>2.3.0-v200706262000</version>
</dependency>
<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>org.eclipse.emf.ecore.xmi</artifactId>
    <version>2.11.0-v20150123-0347</version>
</dependency>

Answer 2

看看different version in the repository。似乎EMF不久前重命名了他们的文物。而不是这个（类似于你的其他EMF依赖）：

<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>ecore</artifactId>
    <version>2.6.1.v20100914-1218</version>
</dependency>

尝试使用此表单（请注意不同的artifactId）：

<dependency>
    <groupId>org.eclipse.emf</groupId>
    <artifactId>org.eclipse.emf.ecore</artifactId>
    <version>2.11.0-v20150123-0347</version>
</dependency>

这里有更新版本。对我来说，2.8以上的每个版本似乎都有效。您还可以使用范围，以始终获得最新版本：

<version>[2.8.0,2.99.99]</version>
