ant build.xml 从 Eclipse 工作，但不能通过命令行

Question

我有以下 ant 文件，它在使用 Eclipse 中的 Run as Ant 文件 运行时构建相应的 jar 文件。注意ant xml文件中没有编译javac任务。

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

后来，我们注意到当我通过 ant -f xxx/build.xml 运行相同的东西时，ant 构建失败，指出没有 bin 文件夹。当我检查我编写的 build.xml 时，很容易理解为什么会失败。有一个任务 <fileset dir="${basedir}/bin"/ 而没有 bin 文件夹。所以我更正了上面的构建文件，如下所示。这样，命令行的构建就通过了。

        </jar>

</project>

我可以理解 eclipse 可能在幕后进行编译，但如果是这种情况，如何确保编写一次的 ant 文件将以相同的方式在任何地方运行？回想起来，触发手动 ant -f xx/build.xml 是最好的。但是想知道任何与蚂蚁有关的细微之处，我可以随时关注。

谢谢， 帕万。
