Using cofoja annotations in IntelliJ

Question

I'm fairly new to IntelliJ. When attempting to use cofoja code annotations I receive the following errors when building.

Error:java: error in contract: package com.google.java.contract.core.agent does not exist
Error:java: error in contract: package com.google.java.contract does not exist

My project is targeting Oracle JDK 1.7. I'm using the version of cofoja that io.konverge released and IntelliJ 14.1.4.

<dependency>
  <groupId>io.konverge</groupId>
  <artifactId>cofoja</artifactId>
  <version>2.0.0</version>
</dependency>

I do not receive encounter errors when building the project from the command line with maven.

EDIT:

Here's a sample cofoja project that compiles fine with maven, but that I cannot build in IntelliJ.

https://github.com/konvergeio/cofoja-example

I've attached the IntelliJ DEBUG build log for this project in a cofoja project ticket on GitHub: https://github.com/nhatminhle/cofoja/issues/45

EDIT 2:

Updated question to be specific to the cofoja-example project.

Answer 1

I was able to successfully configure IntelliJ. Hopefully someone finds this useful.

I had to configure Annotation Processors for the current project. It was enabled by default, but without the appropriate configuration required for classoutput, classpath, and sourcepath settings. I discovered the $PROJECT_DIR$ macro to make relative paths to appropriate project directories. IntelliJ had a pre-configured macro/variable to my local maven repository, so I used that to refer to konvergeio's published version of cofoja.

I took a screenshot of my configuration:

IntelliJ's resulting build log:

2015-07-12 14:04:11,448 [   1223]  DEBUG - s.incremental.java.JavaBuilder - Compiling chunk [cofoja-example] with options: "-g -deprecation -encoding UTF-8 -source 1.7 -target 1.7 -Acom.google.java.contract.sourcepath=/home/seglo/source/cofoja-example/src/main/java -Acom.google.java.contract.classpath=/home/seglo/.m2/repository/io/konverge/cofoja/2.0.0/cofoja-2.0.0.jar -Acom.google.java.contract.classoutput=/home/seglo/source/cofoja-example/target/classes -s /home/seglo/source/cofoja-example/target/generated-sources/annotations" 

I pushed the fork of Nas's cofoja-example project to my github. I included the IntelliJ project settings.
