maven 会为不同的生命周期阶段重新读取 pom 文件吗？

Question

I'm working on creating a maven plugin that will modify version numbers of dependencies in the current pom.xml file.

I can't seem to find any reference about whether maven will re-read the pom.xml file in between lifecycle phases, or whether I can force it to?

The alternative would be to invoke the plugin, and then call the build step after that - but I'd like to do it in one step if it's possible.

Thanks.

This is not possible.

Maven reads the dependencies before invoking plugins, so you need to change the version numbers in a separate Maven run, like

mvn versions:use-releases
mvn clean install

Running one command like

mvn versions:use-releases clean install

will not work.
