Question

我可以让Eclipse导出一个工作正常的独立JAR文件。但是当我尝试将我的build.xml文件与Ant一起使用时，我得到大约100个错误，因为无法解析一堆引用。

这是我的build.xml

  <!-- 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>

这是ivy.xml文件

<ivy-module version="2.0">
    <info organisation="org.herocombatmanager" module="mainwindow"/>
    <dependencies>
        <dependency org="org.apache.commons" name="commons-lang3" rev="3.0"/>
        <dependency org="com.jgoodies" name="looks" rev="2.2.2"/>
        <dependency org="com.jgoodies" name="forms" rev="1.2.1"/>
    </dependencies>
</ivy-module>

以下是一些错误： - ）

[javac] H:\Development\Workspace\HeroCombatManager\src\org\herocombatmanager\XMLParser.java:3: package org.apache.commons.lang3 does not exist
[javac] import org.apache.commons.lang3.StringUtils;

提前谢谢大家..

正如@oers指出的那样，你不能将“lib”目录中的jar文件作为源文件添加，javac任务不能正常工作。

您需要将常春藤解析的罐子添加到ANT类路径中。最简单的方法是使用常春藤cachepath任务，如下所示：

  <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>

请帮我解决我的Ant + Ivy + Java构建/依赖问题
