使用Ant编译源代码时，出错：xxxxx.java is not a directory。谁遇到过，知道怎么解决吗？

Posted 2023-03-15

xxxxx.java就是我想要Ant帮我编译的源文件，结果出了上面所说的错。为什么Ant非要认为xxxxx.java这是一个目录呢？源文件我就是用了一个fileset，加了几个include与exclude稍微改变了一下文件集，以前只要指定目录就会自动找java文件去编译的啊。不知如何解决，请高手指教，在这里先谢过了！

<javac srcdir="$src.dir" 。。。。。。
ant编译的源文件输入是 srcdir，dir顾名思义就是目录的意思。
你可以将你的xxxxx.java所在的目录替换$src.dir,然后试试
<property name="src.dir" value="C:\Program Files\Java\"/> 参考技术A 我编译都是这么整：
<target name="build" description="Compile main source tree java files">
<mkdir dir="$build.dir"/>
<javac destdir="$build.dir" source="1.5" target="1.5" debug="true"
deprecation="false" optimize="false" failonerror="true">
<src path="$src.dir"/>
<classpath refid="master-classpath"/>
</javac>
</target>
给你一个建议，ant的具体用法是不需要太深入的了解，会读会用会改会copy，就能基本应付工作中所有问题了。我以前还是自己写ant，到后来发现没什么必要，现在用的ant就是从hibernate中帮助文档里找来的，功能很全面，常用的都有了。
