在gwt中将jar添加到ant类路径中

Question

我是gwt和ant的新手。早些时候，我正在使用maven/sspring-playFramework/sbt。

我想在我的gwt项目中添加一些外部jar，比如：

• gwt3引导
• 休眠
• mysql连接器等

我已将jar添加到项目中的lib文件夹中：-gwt束带3-0.9.1.jar-gwtbootstrap3-extras-0.91.jar

但我在控制台上得到了一个错误：

我还尝试在项目->属性->Java构建路径->库选项卡->添加外部JAR 上使用eclipse RMB添加这个jar

但这对我没有帮助。

请给我一些帮助。

我已经搜索了很多论坛帖子中的相同问题，但无法自行解决。

只需使用gwtBootstrap3，您就必须下载它的jar！这里是链接

比您必须在build.xml 中声明pathelement

<path id="project.class.path">
        <pathelement location="war/WEB-INF/classes" />
        <pathelement location="${gwt.sdk}/gwt-user.jar" />
        <pathelement location="yourpathtojar/gwtbootstrap3-0.9.1.jar" />
        <fileset dir="${gwt.sdk}" includes="gwt-dev*.jar" />
        <!-- Add any additional non-server libs (such as JUnit) -->
        <fileset dir="war/WEB-INF/lib" includes="**/*.jar" />
    </path>

如果您使用maven项目，则可以遵循以下示例
