Question

我正在尝试编译ActionFactory.java文件，该文件导入我的一个包，RegisterAction.java

这是文件结构：

/com/masatosan/actions/register/RegisterAction.java

/com/masatosan/redirector/ActionFactory.java

根据ANT输出，我认为ANT找不到在ActionFactory.java中导入的RegisterAction.java

当我在控制台上手动运行javac时它会成功编译，所以这必须是ANT没有看到的一些类路径设置。

我知道我可以在ANT_HOME / lib中添加一些jar但在我的情况下，ANT似乎无法找到ActionRegister.java，而不是jar或其他东西。任何人都可以帮我找出问题所在吗？

ANT脚本

<project name="CompileMasatosan"  default="main"
    basedir="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan">
    <description>
        masatosan compiler
    </description>

    <!-- this invokes all targets -->
    <target name="main" depends="compileAll" />

     <!-- properties -->
    <property name="srcMasatosan" 
        location="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\src\com\masatosan" />

    <property name="dest"
    location="C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\head_first\WEB-INF\classes" />

    <property name="redirectorSrc" location="${srcMasatosan}\redirector" />

     <!-- complie -->
    <target name="compileAll">
        <javac target="1.5" source="1.5" srcdir="${redirectorSrc}" destdir="${dest}" />
    </target>

</project>

Answer 1

看起来你只指定了一个“javac”的“sourcepath” - 而不是两者。也许你应该做

<target name="compileAll">
  <javac target="1.5" source="1.5" destdir="${dest}">
    <src path="${redirectorSrc}"/>
    <src path="${srcMasatosan}"/>
  </javac>    
</target>

Answer 2

Make it point to your exact jar files directory where jars are present
<path id="classpath">
<fileset dir="${main.jar}" includes="**/*.jar"/>
<!-- <pathelement location="${src.dir}" />-->
</path>

----in my case jar files present in ----
<property name="main.jar"     value="jar"/>

ANT - 由于找不到符号而导致javac编译失败
