IJ (your best friend in Liferay)

https://github.com/holatuwol/liferay-intellij

Script that generates all the IML files, library descriptors, and the modules.xml file needed to have a complete Liferay project that successfully resolves imports in JSPs and Java files across the 1000+ modules in Liferay.

IJ - Setup

git clone git@github.com:holatuwol/liferay-intellij.git

Add function to .bashrc or functions.zsh

ij() {
  <IJ_CLONE_PATH>/intellij "$@"
}

IJ - Usage

Change directory to liferay-portal

cd <path-to-liferay-portal>

To generate the IntelliJ project after ant all

ij

To generate IML files for a new module you add later on

ij <path_to_new_module>
