在尝试构建我的 Struts 应用程序时，我收到以下错误：

BUILD FAILED

我的包层次结构是src/com/sp/action/*.java和src/com/sp/domain/*.java

我的构建文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project name="strutsComple" default="compile">
    <target name="compile">
        <fileset dir="/media/Data/Works/struts-2.3.1.2/lib/" includes="*.jar"/>
        <javac srcdir="./com/sp/"/>
    </target>
</project>

我已经将两个必需的 jar 添加到我的 Eclipse 文件夹中。

有人可以指出我所缺少的吗？

你的 ant 构建文件太简单了。将 struts jar 导入 eclipse 对您的 ant 构建没有任何作用。您需要在 build.xml 中为 javac 配置一个类路径。

<fileset dir="/media/Data/Works/struts-2.3.1.2/lib/" includes="*.jar"/>
<javac srcdir="./com/sp/"/>

应该成为

<javac srcdir="./com/sp/">
    <classpath>
        <fileset dir="/media/Data/Works/struts-2.3.1.2/lib/" includes="*.jar"/>
    </classpath>
</javac>

请参阅此答案以获取另一个示例让 Ant <javac> 识别类路径

另请参阅javac任务的文档。
