MojoException- Vaadin无法编译

时间：2018-05-23 11:46:14

标签： maven deployment vaadin

我目前正在尝试部署并遇到一些问题。在cmd中运行mvn compile时会出现Mojo错误。我已经附加了我的POM和错误发生的堆栈跟踪，任何帮助将不胜感激。我正在使用Intellij来构建将部署到TOMCAT服务器的WAR，并在Vaadin 8书中注明，您需要将视图类编译成JAR并将它们放在应用程序中。 Webapp＆gt; WEB-INF＆gt; classes文件夹，是否有自动执行此操作的方法？认为这可能是错误发生的原因？我对Vaadin的发展非常不知所措。

答案 0 :(得分：0)

错误显示在堆栈跟踪中，特别是：

Caused by: org.apache.maven.plugin.MojoExecutionException: Command [[
C:\Program Files\Java\jdk1.8.0_171\jre\bin\java -Xmx1G -Dgwt.persistentunitcache=false com.google.gwt.dev.Compiler -logLevel INFO -style OBF -war D:\Programming\NewForest\target\classes\VAADIN\widgetsets -localWorkers 12 -failOnError -XfragmentCount -1 -sourceLevel auto -gen D:\Programming\NewForest\target\.generated WEB-INF.images.archetype-application-example-master.mockapp-widgetset.src.main.resources.org.vaadin.mockapp.MockAppWidgetset
]] failed with status 1

它试图生成的widgetset与Vaadin的Widgetset不匹配，因此导致编译错误。答案是删除widgetset，这意味着编译器默认为Vaadins widgetset。
