ant - CreateProcess error = 2从Ant运行Javadoc

Question

谁能告诉我为什么我收到此错误消息

Buildfile: C:\Users\Tara\workspace\Testing\build.xml
doc:
   [delete] Deleting directory C:\Users\Tara\workspace\Testing\doc 
    [mkdir] Created dir: C:\Users\Tara\workspace\Testing\doc 
  [javadoc] Generating Javadoc
  [javadoc] Javadoc execution

BUILD FAILED
C:\Users\Tara\workspace\Testing\build.xml:24: Javadoc failed: java.io.IOException: Cannot run program "javadoc.exe": CreateProcess error=2, The system cannot find the file specified

Total time: 206 milliseconds

当我在Eclipse中运行时？

<project name="SimpleBuildScript" basedir="." default="doc">
<property file="build.properties"/>
<target name="compile" description="Compiles the Task">
    <delete dir="${class.dir}"/>
    <mkdir dir="${class.dir}"/>
        <javac srcdir="src" destdir="classes"/>
</target>

<target name="clean" description="Delete all generated files">
        <delete dir="${class.dir}"/>
        <delete dir="${jar.dir}"/>
</target>

<target name="doc" description="generate documentation">
    <delete dir="${doc.dir}"/>
    <mkdir dir="${doc.dir}"/>
        <javadoc sourcepath="${source.dir}" destdir="${doc.dir}"/>
</target>
</project>

假设您已经安装了jdk并将其添加到Eclipse：


Windows->首选项Java->已安装
JRE->添加


那你可以


右键单击build.xml
选择Run As-> Ant Build ...注意省略号！
切换到JRE标签
从列表中选择jdk


归功于类似的解决方案：
