As for the timing of this announcement, Oreshnikova said that it took them some time to extact the IntelliJ platform and get it ready for open source usage. "Open Source has really become mainstream and a proven approach to delivering software, so we want to leverage all the positive effects of open source and we think it’s the right time to do this now."
IntelliJ IDEA 9.0 will feature two editions:
Community Edition: Free, Open Source
- Supports Java, Groovy, XML, and Regexp
- JUnit and TestNG testing
- Subversion and Git support
- Ant and Maven build integration
Ultimate Edition: Personal license $249, Commercial license $599
- Grails, Rails, Servlets 3.0, Hibernate frameworks available
- Apache Tomcat, Glassfish v2 and v3 application server support
- OSGi backing and PHP support.
The complete comparison between the two versions can be found here. The release of IntelliJ IDEA 9.0 is scheduled for late November.
The IntelliJ IDEA platform is now open source as well. JetBrains CEO Sergey Dmitriev says his company has always been involved in open source with early access programs and issue trackers. They've also developed open source plugins for IntelliJ IDEA. "In brief, we're not changing direction — we're moving forward," he said.
JetBrains' path forward will have a significant impact on the IDE market since it is the last major Java-based IDE provider to go open source. They will now a enter a playing field that includes open source veterans Eclipse and NetBeans. Ann Oreshnikova had this to say about IDEA's new position: "We suspect that the actual competition will just start with this announcement; formerly we were simply in different fields: free tools vs. a commercial one." Oreshnikova says this competition will be healthy, "This fact should be beneficial for the entire community, because the stronger the competition the faster the innovation."
