Question

尝试构建一个eclipse插件。当我尝试运行mvn install时，我收到以下错误消息：

java.lang.NoClassDefFoundError: org/eclipse/xtext/common/types/DefaultCommonTypesRuntimeModule
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:800)
        at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
        at java.net.URLClassLoader.defineClass(URLClassLoader.java:449)
        at java.net.URLClassLoader.access$100(URLClassLoader.java:71)
        at java.net.URLClassLoader$1.run(URLClassLoader.java:361)
        at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:354)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:425)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)

显然，NoClassDefFoundError意味着该类在运行时不可用。这个插件实际上并不运行xtext代码，但它是使用xtext语言插件构建的。我的猜测是在运行时获取代码会有问题吗？我maven安装了父插件，甚至通过maven在本地链接它的jar，这仍然会弹出。想法？

这也是该项目的主题：

尝试将以下依赖项添加到pom.xml

<dependency>
    <groupId>org.eclipse.xtext</groupId>
    <artifactId>org.eclipse.xtext.common.types</artifactId>
    <version>2.8.4</version>
</dependency>

尝试使用maven安装项目时获取NoClassDefFoundError
