无法在 Vaadin Maven 项目上运行 mvn vaadin:compile

Question

当我运行命令时：mvn vaadin:compile 我得到这个错误：

[INFO] BUILD FAILURE

我进行了搜索，发现我必须将其添加到我的 pom.xml 下：

我添加了，但我仍然收到错误。有没有我必须添加的罐子或其他东西才能完成这项工作？

有关信息，我正在尝试在我的 Vaadin 项目上创建自定义小部件。他们说here 我必须运行 vaadin:compile 来编译 WidgetSet。

我不是 maven 专家，但这是我的 pom.xml，它可以工作。只需确保将<version> 更改为您使用的任何版本的 Vaadin（我的是 7.1.12）。

<build>
    <pluginManagement>
        <plugins>
            <plugin>

                    <target>1.6</target>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>maven-clean-plugin</artifactId>

                </executions>
            </plugin>
    </pluginManagement>
</build>

Answer 2

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，但并未实际使用该插件。

您现在需要在<build><plugins> 元素中定义插件。像这样的：

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

Answer 3

看看pom.xml from Vaadin's demo。

也许goals 不正确，请尝试以下操作：

<goals>
    <goal>resources</goal>
    <goal>update-widgetset</goal>
    <goal>compile</goal>
    <goal>update-theme</goal>
    <goal>compile-theme</goal>
</goals>
