这不是一个很好的解决方案，但是如何一起删除注释呢？
<target name="build-brand" depends="-init" description="Adds version information to branding files."> <propertyfile file="${basedir}/branding/core/core.jar/org/netbeans/core/startup/Bundle.properties"> <entry key="currentVersion" value="${app.windowtitle} ${app.version}" /> </propertyfile> <replaceregexp file="${basedir}/branding/core/core.jar/org/netbeans/core/startup/Bundle.properties" match="^#.*n" replace=""/></target>
