在gwt中将JAR添加到ant类路径

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

我想在我的gwt项目中添加一些外部JAR，如：

• GWT3自举
• 冬眠
• mysql连接器等

我已将JAR添加到项目中的

lib

文件夹中： -gwtbootstrap3-0.9.1.jar -gwtbootstrap3-extras-0.9.1.jar

但我在控制台上遇到一个错误：

我还尝试在EclipseRMB中的项目->属性->Java构建路径->库选项卡->添加外部JAR中添加这个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，但是我自己无法解决这个问题。

只要使用gwtBootstrap3，你就必须下载jar

然后必须在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>

谢谢。但我已经放弃了。我换成了maven，谢谢。但我已经放弃了。我换成了maven。
