问题描述
我试图从wsdl文件生成源代码，但是我仍然遇到我的pom.xml错误，我认为这可能是我的问题？以下是我从我的pom和我的pom文件中得到的错误。另外我无法使用mvn clean install来构建项目。我似乎没有真正的错误。生成标签的错误：

解决方案
在< pluginManagement> 标签内附加< plugins> 标签（如下所述：）为我解决了问题。
Im trying to generate sources from a wsdl file, but I keep running into an error on my pom.xml that I believe might be my issue? Below is the error that I get from my pom, and my pom file. Also I cannot build the project with "mvn clean install". I just seem to get an error with no real cause.
The error at the generates tag:
Execution default of goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate failed: A required class was missing while executing org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate: com/sun/codemodel/CodeWriter

解决方案
Enclosing the <plugins> tag inside <pluginManagement> tag (as detailed here: How to solve "Plugin execution not covered by lifecycle configuration" for Spring Data Maven Builds) fixed the issue for me.
