IntelliJ Modules Setup Script

local

This script 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.

If you're more of a visual person and would like screenshots to better understand what that actually means, check the ABOUT file.

Setup Instructions

To setup the script, please use the following steps.

Install NodeJS (tested with NodeJS 0.12.x, 4.x, 6.x, and 8.x), or use Node Version Manager to allow for multiple versions of NodeJS (needed if you need to work on legacy frontend code)
Backup the .idea folder in your portal source in case you dislike the result (other than the .iml files it creates, the script writes its files here)
Clone this repository.

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

Add a Bash function that makes it easy for you to call it and do any other setup. Replace /path/to/clone/location with the path to the liferay-intellij folder that you created by cloning the repository in step 3.

IJ_CLONE_PATH=/path/to/clone/location

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

Typical Usage Instructions

There are a few different ways to use this script, which are documented below. Once you've followed the instructions, have IntelliJ open the project rooted in the folder where you ran the ij function, and it will load your populated project!

Public Source

To load a project containing only the portal source for a public repository, follow these instructions.

Navigate to where you've cloned the liferay-portal repository
Run the ij command (no parameters) to generate the IntelliJ project

cd /path/to/portal/public/source
ij

Private Source With Public History

If you'd like to work with master-private or 7.0.x-private and you need the history on the master and 7.0.x branches, follow these instructions.

Navigate to where you've cloned the liferay-portal repository
Run the ij command, and specify the path to where you cloned the liferay-portal-ee repository and checked out the corresponding private branch

cd /path/to/portal/public/source
ij /path/to/portal/private/source

Private Source Without Public History

If you'd like to work with master-private or 7.0.x-private and you don't need the history on the master and 7.0.x branches, follow these instructions.

Navigate to where you've cloned the liferay-portal-ee repository
Run the ij command (no parameters) to generate the IntelliJ project

cd /path/to/portal/private/source
ij

Public Source With Subrepositories

To load a project containing only the portal source for a public repository and the code for all public/private subrepositories that you've checked out, follow these instructions.

Navigate to where you've cloned the liferay-portal repository
Run the ij command, and specify as an argument the path to where you cloned the various subrepositories. If you have them all cloned inside of one parent folder, just specify the one parent folder and it will locate them all!

cd /path/to/portal/public/source
ij /path/to/subrepo1 /path/to/subrepo2 /path/to/subrepo3

cd /path/to/portal/public/source
ij /path/to/subrepos

Private Source With Public History and Subrepositories

To load a project containing only the portal source for a public repository and the code for all public/private subrepositories that you've checked out, follow these instructions.

Navigate to where you've cloned the liferay-portal repository
Run the ij command, and specify as an argument the path to where you cloned the liferay-portal-ee repository and checked out the corresponding private branch, and specify the various subrepositories. If you have them all cloned inside of one parent folder, just specify the one parent folder and it will locate them all!

cd /path/to/portal/public/source
ij /path/to/portal/private/source /path/to/subrepo1 /path/to/subrepo2 /path/to/subrepo3

cd /path/to/portal/public/source
ij /path/to/portal/private/source /path/to/subrepos/parent

Atypical Usage Instructions

There are a few features for atypical scenarios as well.

Command Line Flags

There are a few command-line flags that you can pass to ij in order tell it to do some extra processing.

--barebone: unload modules that aren't required by portal-impl to improve IntelliJ startup speed (must manually reload any module you actually use)
--complete-cache: download any dependencies not present in your local Maven and Gradle caches (prefer Maven, if available, since it will persist across builds)
--ic: do not add any web facets, so that the project is compatible with IntelliJ community edition
--unload: unload modules that aren't built as part of ant all to improve IntelliJ startup speed
--unzip: unzip existing .jar files from a Liferay Tomcat bundle into the build folders of your project

Plugins SDK and Blade Workspace

All folders that you specify as arguments will be assumed either to be an Ant-based Plugins SDK root (designated by the presence of build-common-plugins.xml), a Blade workspace (designated by the presence of a gradle.properties), or a folder used to store subrepositories (such as those generated by forking subrepositories OR the modules folder of the master-private and 7.0.x-private branch).

ij /path/to/folder1 /path/to/folder2 /path/to/folder3

Other Caveats

The script generates .iml files that are slightly different from the ones that have been committed to Liferay's version control, so the alias adds all .iml files to an ignore list. You can clear your ignore list with the following.

git ls-files -v | grep '^h ' | cut -d' ' -f 2 | xargs git update-index --no-assume-unchanged
