Question

我有一个使用JAXWS插件的maven项目，使用wsimport基于WSDL生成一些代码。如果我运行mvn generate-sources，则会生成此代码。

此外，我还有JUnit单元测试，它引用了生成的类。

根据默认安装中的docs，测试应该在generate-sources之后运行，因此它应该可以工作。但是，如果我在eclipse中的干净工作区上运行构建，我会为其中一个生成的类获取NoClassDefFound。如果你再次运行安装它就可以了。

这有点奇怪所以我退出了eclipse并回到了命令行的基础知识。如果我执行此序列，则会收到NoClassDefFound错误：

mvn clean
mvn install

但是，如果我执行以下操作，则无错误地运行：

mvn clean
mvn clean install

这怎么可能？我原以为mvn clean install会相当于mvn clean + mvn install吗？

此外，当它出错时，我可以在控制台输出中看到代码生成阶段在进行测试之前实际运行。课程就在那里，但是类加载器显然无法看到它。

我在控制台输出中没有看到任何其他错误。关于指定插件版本号和源文件的一些警告是在cp1252中编码的。没什么好激动的。

我确实读过这个question但它并没有帮助我。我正在使用Java 8 jdk，所以我想知道这里是否有错误。

修改

我不确定代码在这种情况下是否有用，因为您无法在没有完整代码库的情况下运行测试版本。但是，它可能有助于查看pom和构建步骤的复杂性，因此这里是一个经过编辑的版本。我刚刚重命名了一些东西，使其更加匿名，但在功能上却是相同的。

希望它有助于解决所提出的问题。

Answer 1

我一直在重新审视这个项目，并重新审视了这个问题。我经历了pom并仔细检查了所有可以修剪或更新的东西。在这个过程中，我发现了以下插件。

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.2.1</version>
    <configuration>
        <mainClass>org.test.int1.Main</mainClass>
    </configuration>
</plugin>

我认为当我们刚开始使用maven时，必须从某个例子中复制这个。该插件是在构建期间执行Java程序，我不需要它，并且主类不存在。尽管如此，我还没有得到任何关于此的构建警告。

删除该插件可解决问题。这修复了它在命令行上，对于Eclipse，我还必须右键单击项目并选择Maven，然后选择Update project。

在maven clean build的单元测试中使用生成的代码？
