The following instructions are for IntelliJ IDEA 14.x. Later versions changed how multi-module Maven projects get imported: it imports them in a flat structure rather than grouped per top-level project, which means that you have to group them yourself again in the Project structure dialog.
You can import ADAMS using the start screen of IntelliJ by clicking on Import project:
Or by selecting File -> Import project... from the main menu.
Then, select the top-level directory of ADAMS and import it as Maven project:
- import module from external model: Maven
- check import Maven projects automatically
- check create module groups for multi-module Maven projects
- select any relevant Maven profiles (or just use all of them)
If you want to add other projects, like adams-addons or adams-incubator, you must import them via File -> Project structure... from the main menu. There, select Modules and when clicking on the green plus sign, select Import module.
Once you've imported ADAMS, you can configure the JDK that you want to use (1.8 at the time of writing). For this, open Project structure from the main menu.
Under SDKs you can define all the SDKs that you want to be able to use (simply click on + and select the top-level directory of your JDK):
And under Project, you can then select the SDK that you want to use for the project:
ADAMS uses mixed spaces/tabs for indentation, with indentation being 2 spaces and a tab representing 8 spaces.
Usually, you don't want to compile when you launch the application, but whenever you change the code. Hence, enable auto make:
Despite having auto make enabled, it pays off to have a build action before launching applications. Hence change the Before launch action to use Make, no error check. Furthermore, you will most likely have the module's top level directory as the default working directory when starting up the application. You can set this using the $MODULE_DIR$ variable.
There are a plethora of color themes for IntelliJ out there, in case you don't like the ones it is shipped with:
For creating a launcher (or Run configuration), you select Run -> Edit configurations... from the main menu. When clicking on the +, use Application as template and fill in adams.gui.Main as the main class and the amount of RAM that you want to use, eg 2GB:
Whether you want to launch your image editing tool (e.g., Gimp for creating icons) or launching Maven to auto-generate code (e.g., when using Apache CXF), then you can use IDEA's External tools facility:
- Starting with version 2016.1, IntelliJ bundles its own JRE (based on OpenJDK). However, the font rendering can some times leave much to be desired. The Oracle JDK/JRE performs better font rendering (e.g., on Linux) and you can point IntelliJ to the JDK/JRE it should use by simply setting the IDEA_JDK environment variable (source).
- For large projects like ADAMS you may have to increase the heapsize for the Maven Importer in your settings, as 512MB might not be enough, and despite the code compiling on the command-line, IntelliJ IDEA listing lots of failed imports from other modules. Use something like -Xmx1024m in Build Tools -> Maven -> Maven -> VM Options for importer.
