无法运行mvn vaadin:编译Vaadin Maven项目

Question

当我运行命令时:mvn vaadin:compile我收到此错误:

[INFO] BUILD FAILURE

我进行了搜索,发现我必须将其添加到我的pom.xml中:

<pluginManagement>
  <plugins>
    <!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->

                <versionRange>
                  [${gwt.plugin.version},)
                </versionRange>
                <goals>
                  <goal>resources</goal>

          </pluginExecutions>
        </lifecycleMappingMetadata>
      </configuration>
    </plugin>
  </plugins>
</pluginManagement>

我补充说,但我仍然得到错误.是否有任何罐子或东西需要添加才能使其工作？

有关信息,我正在尝试在我的Vaadin项目上创建自定义小部件.他们在这里说我必须运行vaadin:compile来编译WidgetSet.

您已将插件配置放入pluginManagement 部分，该部分仅定义了一些默认配置，但并不实际使用该插件。

您现在需要在元素内定义插件<build><plugins>。像这样的东西：

<build>
    <plugins>
        <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
        </plugin>
    </plugins>
</build>
