I pointed the p2 installer at the Java 9 Beta software site and installed both features (one is the feature and the other is the corresponding source code). I launched Eclipse and opened the p2 installer using the Help > Install new software. Note that this change occurs before the -vmargs line. Offline Repository Packages Aqua Product Name IM Zip Download P2 Zip Download Minimum Prerequisite. IBM CICS Configuration Manager cm: 3.2 3.3: p2 IM ZIP. I made a small change to the eclipse.ini file to make the new configuration run using the Java 9 runtime. Note: Aqua 3.1 is based on Eclipse V4.6 Neon, Aqua 3.2 is based on Eclipse V4.8 Photon, and Aqua 3.3 is based on Eclipse V4.23. I downloaded the Eclipse SDK 4.6 (Neon) M2 from the Eclipse Platform downloads and decompressed it into its own directory. I downloaded the early access version of Java 9 JDK from in the form of a tar.gz file that I decompressed into a local directory: /home/apps/jdk1.9.0. It’s a work-in-progress, but certainly shows that progress is being made. I’ll admit to a certain amount of shame that it’s taken me this long to try out the Beta Java™ 9 support in Eclipse. Update: Note that as of October 11/2017, Java 9 is 100% supported “out of the box” by Eclipse IDE, Oxygen Edition Java 9 can be used to run your Eclipse IDE, Oxygen Edition, and can be used to build Java 9 applications without additional configuration.
