是否可以从Ant中的命令行生成文件“ build.xml”？

Question

I am looking to script my build process. Currently I am able to build the build.xml file manually, and then run the following command to create the JAR file:

    system("ant -f ~/build.xml")

I would like to rebuild my build.xml file every time I run this script so that I ensure all changes are in the build.xml file. Is there an Ant command I can run to build this build.xml file?

For reference, I am using IntelliJ IDEA currently to create my build.xml file.

There are other common ways to customize your build in Ant. Like:

• Introducing properties (possibly excluded to the build.properties file) and
• regular expressions wherever feasible.

These should cover most of the use cases in Ant.

For the more sophisticated stuff, you can even go for more logic using ant-contrib tasks .

As an alternative:

• If you'd still like to stick with generation of the custom build.xml file every time, you could go for some XSLT transformation where you would do so. But that is not a common practice, I'd say. Or
• go for Maven , as suggested in the comment or even
• go for Grails

However, to help you choose the fitting solution, you should tell us some more details on the build.xml changes you'd like to achieve.
