使用以下内容创建 build.xml −
Create build.xml with the following content −
<?xml version="1.0"?>
<project name="TutorialPoint" default="info">
<property name="build.dir" value="build" />
<target name="info">
<fail unless="src.dir"/>
</target>
</project>上面的脚本将使构建失败，因为未设置 src.dir。
Above script will fail the build as src.dir is not set.
