spring 以Ant Build方式运行build.xml文件，报warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds 的解决办法

Buildfile: F:\experience\spring_pdf\sourcecode\example1\build.xml
compile:
    [javac] F:\experience\spring_pdf\sourcecode\example1\build.xml:25: warning: ‘includeantruntime‘ was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds

BUILD SUCCESSFUL

只需要根据提示在javac任务中添加includeAntRuntime="false"属性即可。

1         <javac destdir="classes" source="1.5" target="1.5" includeAntRuntime="false"
2                 deprecation="false" optimize="false" failonerror="true">
3             <src path="src"/>
4             <classpath refid="lib"/>
5         </javac>
