!!IntelliJ does not start with OSX Yosemite (no Java 1.6 installed)
With version Yosemite, OSX no longer bundles Java 1.6. Because of that, we have to tell IntelliJ to use the Java 1.8 (or newer) runtime instead. The best way to do this is to put a file "idea.properties" into the directory {{~/Library/Preferences/IntelliJXX/}}, specifying the correct runtime. You can also specify other properties like console buffer size and so forth. Your properties file could look like this: [idea.properties]. It's also ok to just use this file.
!!Create a new Plugin-Module
* right click on the respective parent module
* "new" -> "Module"
* select "Maven"
* select no archetype when asked
* Enter the name of your plugin for "Module Name"
* Change the entry of "Content root" using the "..." button, create new subfolder within the parent module named according to your plugin name, select this folder for "Content root" and "Module file location"
* hit next/finish
* (if your intelliJ is not configured to auto-import maven modules:) Import the project as maven module

Also, under Settings, go to "File and Code Templates" (use search bar in Settings) and in the tab "Includes" adapt your File Header. Instead of the "Created by ... on... " use the following:

!!Use Identical Path for JUnit and Maven Testing
Unfortunately JUnit in IntelliJ IDEA has a different path for executing JUnit tests in modules as it will have when testing in maven builds. You can change this unwanted default behaving by setting the default JUnit path in the Run Configuration default settings for JUnit:
Open Menu {{Run->Edit configuration}} and there go to {{Defaults->JUnit->Working directory}} and set the value to {{$MODULE_DIR$}}.
[{Image src='JUnit Default Path Setting.png' height=400px}]
After that IntelliJ IDEA will set the relative path in all JUnits just like Maven.

%%warning There currently seems to be a problem with the eclipse compiler option using Java 8. If you are getting an error like "Error:java: source level should be comprised in between '1.3' and '1.7' (or '5', '5.0', ..., '7' or '7.0'): 8", switch back to Javac again.

To remove the dock entries that IntelliJ spawns when compiling or running Tomcat, append {{-Dapple.awt.UIElement=true}} to your Java VM options.

!!Migrating to Java 8 and JSPWiki 2.10
At line 183 removed one line
Since the end of July, we migrated KnowWE to now use JSPWiki 2.10, Java 8 and Tomcat 8. Follow this section to migrate your own workspace/project in IntelliJ:
At line 185 removed 3 lines
# Install JDK 8 and add and set it as the default in your JDK. In IntelliJ, go to File -> Project Structure... -> SDKs and add the JDK 8. Under Project also in Project Structure..., set it as the default.
# Download the current Tomcat 8 as the zip version. Unzip it analogous to your Tomcat 6 and set it your Tomcat configurations in IntelliJ.
#jspwiki.properties is now jspwiki-custom.properties. Instead of in local/WEB-INF/ it is now in local/WEB-INF/classes/. It has basically the same content as before, but you should nevertheless start again from the .default file and just migrate your individual settings like var.basedir to the new file.

!!Java 8 and JSPWiki 2.10 issues
At line 193 removed one line
!Java source level error
At line 195 removed 27 lines
If you get an error like:
{{{
"Error:java: source level should be comprised in between '1.3' and '1.7' (or '5', '5.0', ..., '7' or '7.0'): 8"
}}}
you have to switch back to Javac as the compiler again. More info at [IntelliJ FAQ#View all compile errors of the project/workspace]
!SecurityManager/jspwiki.policy issues
If you have an error with content like
{{{
"Failed to start managers: File /IntelliJ%20Workspaces/denkbares/KnowWE-App/target/KnowWE-App-0.2-SNAPSHOT/WEB-INF/jspwiki.policy does not exist, or the SecurityManager prohibited access to it."
}}}
your problem is very likely a whitespace in the path to the jspwiki.policy file. The SecurityManager of JSPWiki 2.10 does not like that.
If the whitespace is in your workspace folder name, you can close IntelliJ, rename the folder, open IntelliJ again and then choose the new folder in the welcome splash screen after clicking "Open Project".
!Error with com.ecyrd.jspwiki....
If you get (class loading) exceptions involving the old pre 2.9. JSPWiki package naming while starting ab KnowWE, you most likely are dealing with one of the following issues:
# You are trying to start KnowWE with an old pre 2.9 JSPWiki plugin like the TablePlugin. Update or remove these plugins in your dependencies.
# There are leftover files in your workspace containing the old JSPWiki code with the wrong package names. Do a "Find in path" with "ecyrd" to quickly find them. Most likely you can delete or update them. In case the files are in one of the "Overlay" folders in KnowWE-Resources or KnowWE-App, you can delete them. Do a maven build afterwards.
