我在eclipse下有一个maven GWT项目,因为我添加了一些服务器端依赖项,所以maven插件不再编译。以下是有关上下文的更多信息:
- 行家3.0.3;
- GWT 1.5.3;
- GWT maven 插件 org.codehaus.mojo:gwt-maven-plugin:1.2(与 GWT 1.5.3 兼容的最新版本, http: //mojo.codehaus.org/gwt-maven-plugin-1.2/)。
如果我不添加 GWT 以外的依赖项,GWT maven 插件的目标 gwt:compile 将成功完成:
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-servlet</artifactId>
<version>${gwt.version}</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>${gwt.version}</version>
<scope>provided</scope>
</dependency>
当我添加任何其他依赖项时,目标 gwt:compile 失败:
[INFO] establishing classpath list (scope = compile)

我确实在 gwt:compile (http://mojo.codehaus.org/gwt-maven-plugin-1.2/compile-mojo.html) 中搜索了有关类路径/依赖项的配置参数,但没有成功。
我想与 GWT 一起使用服务器端依赖项,告诉 GWT 插件不要考虑非 GWT 依赖项。
