【问题描述】：
我的 vaadin 项目有问题。我添加了一个在 vaadin 市场上找到的用于制作 QR 码的插件。为了让一切正常工作，我需要在这个插件中编译小部件集，但这是问题所在。
当我尝试在 Eclipse 中使用用于编译小部件集的按钮或直接使用 mvn vaadin:update-widgetset 时，我收到以下错误：

经过一番研究，似乎没有找到其他一些目标，因为现在当我尝试构建我的解决方案时，我遇到了类似的错误，但有另一个目标：

显然我在我的 pom.xml 中遗漏了一些东西。我是 maven 的新手，我不知道我错过了什么。
这是我的pom：

【问题讨论】：
-
根据错误信息这个插件只有目标：
copy-production-files,package-for-production... -
看this site，看来OP已经设置OK了，我们的pom也设置了类似的，所以你无权访问目标很不寻常
-
检查 vaadin-maven-plugin 的版本和你正在使用的 vaadin 版本它们不符合..我认为应该是这种情况....
