Maven GWT依赖

标签： eclipse gwt maven

我正在尝试安装我的项目。 我一直收到这个错误。我想知道是否有人可以帮助我。如何解决这个问题。

据我所知，它正在尝试编译一些（org.codehaus.mojo：gwt-maven-plugin）maven的插件（jar文件）并且无法在其中找到一些类。如我错了请纠正我。

Maven找不到类org.apache.commons.io.IOUtils。这包含在GWT Dev包中。 考虑将此添加到您的pom：

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-dev</artifactId>
    <version>${gwtVersion}</version>
    <scope>provided</scope>
</dependency>

构建会给你一些关于在你的依赖项中包含gwt-dev的警告，但我从来没有遇到任何问题....
