AIDEGen

AIDEGen aims to automate the project setup process for developers to work on
Java or C/C++project in popular IDE environment. Developers no longer need to manually
configure an IntelliJ project, such as all the project dependencies. It's a
command line tool that offers the following features:

• Configure Android Studio or IntelliJ project files with the relevant module
  dependencies resolved.

• Launch IDE for a specified sub-project or build target, i.e. frameworks/base
  or Settings.

• Launch IDE for specified folder(s) which contains build targets, i.e. cts.

• Auto configure JDK and Android coding style for IntelliJ.

1. Prerequisites:

• IDE installation, choose one of prefer IDE, including Android Studio,
  IntelliJ IDEA, Eclipse, CLion and VS Code.

• Setup Android development environment.

$ source build/envsetup.sh && lunch <TARGET>

2. Basic Usage:

Example 1: Launch IDE with module name

Example to generate and launch IntelliJ project for framework and Settings:

$ aidegen Settings framework

Example 2: Launch IDE with module path

Example to generate and launch IntelliJ project for framework and Settings:

$ aidegen packages/apps/Settings frameworks/base

Example 3: Launch IDE with build skipped

Example to generate and launch IntelliJ project for framework and Settings and
skip build time:

$ aidegen Settings framework -s

Example 4: Launch IDE with native module

Example to generate and launch CLion project:

$ aidegen <module> -i c

The native projects will be launched in CLion and you have to select,
Tools > CMake > Change Project Root
Change project root to the source directory: the relative path which is the directory shown in CLion’s project view. For example, if frameworks/base/media is your project, please change project root directly to frameworks/base/media.

3. Optional arguments:

Developers can also use the following optional arguments with AIDEGen commands.

Option	Long option	Description
-d	--depth	The depth of module referenced by source.
-i	--ide	Launch IDE type, j=IntelliJ s=Android Studio e=Eclipse c=CLion v=VS Code
-p	--ide-path	Specify user's IDE installed path.
-n	--no_launch	Do not launch IDE.
-r	--config-reset	Reset all AIDEGen's saved configurations.
-s	--skip-build	Skip building jars or modules.
-v	--verbose	Displays DEBUG level logging.
-a	--android-tree	Generate whole Android source tree project file for IDE.
-e	--exclude-paths	Exclude the directories in IDE.
-l	--language	Launch IDE with a specific language,j=java c=C/C++ r=Rust
-h	--help	Shows help message and exits.

4. Troubleshooting tips:

If you get an error like: "Dependent modules dictionary is empty." or other errors, try a make
clean.

5. FAQ:

Q1. If I already have an IDE project file, and I run command AIDEGen to generate
the same project file again, what'll happen?

A1: The former IDEA project file will be overwritten by the newly generated one
from the aidegen command.

Q2: When do I need to re-run AIDEGen?

A2: Re-run AIDEGen after repo sync.

6. Hint:

1. In IntelliJ, uses [File] > [Invalidate Caches / Restart...] to force
   project panel updated when your IDE didn't sync.

2. If you run aidegen on a remote desktop, make sure there is no IntelliJ
   running in a different desktop session.
