请帮助我解决我的Ant+；常春藤+；Java构建/依赖性问题

我可以让Eclipse导出一个独立的JAR文件，这很好。但是，当我尝试将build.xml文件与Ant一起使用时，我得到了大约100个错误，因为大量引用无法解析

  <!-- Deletes the existing build, docs and dist directory-->

    </jar>
  </target>

  <target name="main" depends="compile, jar, docs">

</project> 

这是我的build.xml

  <!-- Deletes the existing build, docs and dist directory-->

    <delete dir="${build.dir}" />
    <delete dir="${docs.dir}" />
    <delete dir="${dist.dir}" />

  </target>

提前谢谢大家

正如@oers所指出的，您不能将jar文件作为源文件添加到“lib”目录中，任务不能以这种方式工作

  <!-- Deletes the existing build, docs and dist directory-->
  <target name="clean">
    <delete dir="${build.dir}" />
    <delete dir="${docs.dir}" />
    <delete dir="${dist.dir}" />
  </target>

  <!-- Creates the  build, docs and dist directory-->
  <target name="makedir">
    <mkdir dir="${build.dir}" />
    <mkdir dir="${docs.dir}" />
    <mkdir dir="${dist.dir}" />
  </target>

      <!-- ================================= 
            target: resolve              
           ================================= -->
      <target name="resolve" description="--> retrieve dependencies with ivy">
          <ivy:retrieve />
      </target>

  <!-- Compiles the java code (including the usage of library for JUnit -->
  <target name="compile" depends="resolve,clean, makedir">
    <javac destdir="${build.dir}" includeantruntime="false">
        <src path="${src.dir}"/>
        <src path="${lib.dir}"/>
    </javac>

  </target>

  <!-- Creates Javadoc -->
  <target name="docs" depends="compile">
    <javadoc packagenames="src" sourcepath="${src.dir}" destdir="${docs.dir}">
      <!-- Define which files / directory should get included, we include all -->
       <fileset dir="${src.dir}">
                <include name="**" />
           </fileset>
    </javadoc>
  </target>

  <!--Creates the deployable jar file  -->
  <target name="jar" depends="compile">
    <jar destfile="${dist.dir}\hcm.jar" basedir="${build.dir}">
      <manifest>
        <attribute name="Main-Class" value="org.heromanager.MainWindow" />
      </manifest>
    </jar>
  </target>

  <target name="main" depends="compile, jar, docs">
    <description>Main target</description>
  </target>

</project> 

您需要将ivy解析的JAR添加到ANT类路径。最简单的方法是使用常春藤任务，如下所示：

  <!-- Deletes the existing build, docs and dist directory-->
  <target name="clean">
    <delete dir="${build.dir}" />
    <delete dir="${docs.dir}" />
    <delete dir="${dist.dir}" />
  </target>

  <!-- Creates the  build, docs and dist directory-->
  <target name="makedir">
    <mkdir dir="${build.dir}" />
    <mkdir dir="${docs.dir}" />
    <mkdir dir="${dist.dir}" />
  </target>

      <!-- ================================= 
            target: resolve              
           ================================= -->
      <target name="resolve" description="--> retrieve dependencies with ivy">
          <ivy:retrieve />
      </target>

  <!-- Compiles the java code (including the usage of library for JUnit -->
  <target name="compile" depends="resolve,clean, makedir">
    <javac destdir="${build.dir}" includeantruntime="false">
        <src path="${src.dir}"/>
        <src path="${lib.dir}"/>
    </javac>

  </target>

  <!-- Creates Javadoc -->
  <target name="docs" depends="compile">
    <javadoc packagenames="src" sourcepath="${src.dir}" destdir="${docs.dir}">
      <!-- Define which files / directory should get included, we include all -->
       <fileset dir="${src.dir}">
                <include name="**" />
           </fileset>
    </javadoc>
  </target>

  <!--Creates the deployable jar file  -->
  <target name="jar" depends="compile">
    <jar destfile="${dist.dir}\hcm.jar" basedir="${build.dir}">
      <manifest>
        <attribute name="Main-Class" value="org.heromanager.MainWindow" />
      </manifest>
    </jar>
  </target>

  <target name="main" depends="compile, jar, docs">
    <description>Main target</description>
  </target>

</project> 

  <target name="resolve" description="--> retrieve dependencies with ivy">
     <ivy:resolve/>
     <ivy:cachepath pathid="compile.path"/>
  </target>

  <target name="compile" depends="resolve,clean, makedir">
    <javac destdir="${build.dir}" includeantruntime="false" classpathref="compile.path">
        <src path="${src.dir}"/>
    </javac>
  </target>

Javac需要lib dir位于classmate元素中，而不是src元素中。谢谢你的工作。不幸的是，我遇到了另一个问题。我在进行Ant构建时遇到了这个错误：“类路径引用的归档文件：C:/Program Files/Java/jdk1.6.0!33/lib/tools.jar不存在。”@David听起来你用来运行Ant的JVM不是JDK（与JRE相反）。谢谢你，这正是我需要的。现在我的问题都是XML格式的问题，我可以自己解决。
