Laboratoire ICAR » Plateforme TXM

Change the way the JRE is embedded in TXM.

Current state¶

- we use build.properties commands to copy the "jre" directory to the root of the built app
- problems:
- since we use PDE (unique update for TXM root feature) and not Tycho (separated updates for each bundle), the JRE is embedded in all updates
- on Window, P2 can't remove dll, exe that are in use so our updates fail when trying to uninstall the current root feature

Solution 1¶

- use 3 optional features, 1 for each OS JRE
- use a master feature that drives the native features
- use p2.inf and setJVM instruction to set the launcher JVM path at first install or at a JVM update
- pros:
- improve the management of JRE versions
- should fix the Window update bug
- lighten the updates by not including the JRE in all updates
- improve debug and testing by changing the JRE version
