Question

我使用webAppCreator制作了一个示例GWT应用。

运行任何mvn命令时，例如mvn package，我收到此错误：

[WARNING]行说明了所有内容 - 您需要在<type>pom</type>中将dependencyManagement添加到pom.xml。

打开pom.xml并更改以下部分：

  <dependencyManagement>
    <dependencies>
      <!-- ensure all GWT deps use the same version (unless overridden) -->
      <dependency>
        <groupId>com.google.gwt</groupId>
        <artifactId>gwt</artifactId>
        <version>${gwtVersion}</version>
        <scope>import</scope>
        <type>pom</type>
      </dependency>
    </dependencies>
  </dependencyManagement>

为：

  <dependencyManagement>
    <dependencies>
      <!-- ensure all GWT deps use the same version (unless overridden) -->
      <dependency>
        <groupId>com.google.gwt</groupId>
        <artifactId>gwt</artifactId>
        <version>${gwtVersion}</version>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

这是[{1}}：https://code.google.com/p/google-web-toolkit/issues/detail?id=9054中的已知错误。将GWT更新到最新版本。（感谢Thomas Broyer）。
