如何从蚂蚁脚本中删除java System.out.println

Question

how to remove java System.out.println from ant script? (when we compile the code from ant we should remove the existing java class system.out.println & compiled classes should not have the Sys.out.println)

Answer 1

In build.xml file, preparation phase, before the mkdir commands, provide:

<javac srcdir="exe" includes="SysOutRemove.java"/>
<java fork="true" classname="SysOutRemove" dir="exe" failonerror="true"/>

where SysOutRemove.java is in the exe package of your project.

SysOutRemove.java should iterate through the list of directories and files in them, store the contents of each file to a reader or something, find sysout statements and replace.

Answer 2

We can use this in the ant file.

 <replaceregexp match="System.out.println(.*);" replace="" flags="g" byline="true"> <fileset dir="${src.dir}" includes="**/*.java"/> </replaceregexp>
