====== IDEA ======

{{tag> ide}}

Configuration quickstart for developing CzechIdM in IntelliJ IDEA.

====== Import project ======

  - Open Idea and choose to //Import project (File → New → Project from Existing Sources)//
  - Import the ''/–path–/CzechIdM/Realization/backend/aggregator''  project, where ''–path–''  is wherever you pulled your sources, click //Next//
  - {{  .:importmaven.png?nolink&460x581  }}The aggregator project should import all dependencies automatically, give it some time.
  - Next. Next… Project should be imported.
  - Make sure to set dev profile in the maven panel on the right
  - {{  .:dev-profile.png?nolink&269x556  }}You should be good to go.

====== Metamodel generation ======

After creating the project, make sure following modules are available in explorer:

  * ic
  * acc
  * core-api
  * core-impl
  * core-test-api

To set up metamodel generation, go to "File → Settings → Build, Execution, Deployment → Compiler, Annotation Processors" and tick "Enable annotation processing". Now rebuild the project.

====== Code style ======

Go to "File → Settings → Editor → Code style → Java". On the first tab, "Tabs and indents", tick "Use tab character". On next tab "Imports" put 999 to "Class count to use import with '*'" and "Names count to use static imports with '*'.

Next adjust the Import Layout on the bottom of the window as:

<code>
static all other,
blank,
java.*,
blank,
javax.*,
blank,
org.*,
blank,
com.*,
blank,
all other imports

</code>

====== Configure test runner ======

<note warning>This currently doesn't seem to work, alternative is to just check the test profile in Maven and run specific tests over one folder by right-click > run tests in java</note>

To create test run configuration for all modules (including 'acc'), go to Run/Debug Configuration, click '+' and choose 'JUnit'. Use following settings:

  * Test kind: All in package
  * Package: eu.bcvsolutions.idm
  * Search for tests: whole project
  * Before launch: Build
  * Add to VM options following: -ea -Dspring.profiles.active=test

<note important>**-Dspring.profiles.active=test**  ||| This is the only way how you can run tests under profile test. It is also used for a single test.</note>

Save the configuration and test it by running. Tests from all modules should be executed.

====== Launch on Tomcat ======

First of all make sure that you have Tomcat 9.0 installed. Then chose Tomcat server in Run/Debug Configurations in IDEA. Set URL to "http://localhost:8080/idm-backend/". On a "Deployment" tab set Application context to ''idm-backend/''. Apply and try to launch the project on server. At this point I had an error that said something like "name or service not known", there is the link that helped me solving this error: "https://stackoverflow.com/questions/19068977/intellij-cant-start-simple-web-application-unable-to-ping-server-at-localhost".

TIP 01: Deploy exploded artefact instead of compressed one.

TIP 02: If there is nothing deployed to the server check File → Project Structure → Artefacts tab. Add all modules you want to deploy to the artefact you deploy. This should happen automatically by Maven but sometimes it doesn't.

====== Importing a Module ======

To develop a module alongside main CzechIdm, import the module from Project Structure > Project Settings > Modules > Right click in the list of modules > Add > Import Module

{{.:screenshot2023-12-04153509.png?nolink&1035x921}}

When the module is imported, go to Artifacts tab and drag the module artifact over idm-backend.war.

{{.:idm-war.png?nolink&855x579}}

Then rebuild the project.

<note important>When you reload Maven configuration, this change will disappear and you have to re-add the module to war again</note>


===== Troubleshooting =====

If you see errors with missing dependencies, try to reload Maven profiles (double-shift > reload Maven).

If that doesn't help, try to rebuild project from command line ''mvn clean install -DskipTests''
