TTworkbench: How to change the built-in JDK setting for TTworkbench to my own one?
Objective/Summary
Change the built-in JDK setting in TTworkbench to use an other version
Environment/Versions
TTworkbench 28 or newer
Microsoft Windows/Linux
Procedure
Close TTworkbench and modify the
ttworkbench.ini
file (located in TTworkbench installation directory) with any text editor by adapting the "
-vm
" option line :
-vm jdk/bin
The line with the -vm option must point to your JDK bin directory e.g.:
-vm
C:\Java\open-jdk13.x.x\jdk13.x.x\bin\
-vmargs
...
Alternatively, you can change the version at run-time in Window > Preferences > Execution - TTman > Use specific java version.
Notes
Which Java is currently used can be seen in Help > About TTworkbench > Installation Details > Configuration tab
To be absolutely safe, the JDK directory in the TTworkbench installation can also be deleted after the change (in case of using an other version)
The TTworkbench 29 package contains an OpenJDK 13 installation in the "jdk" subfolder of the TTworkbench installation folder
The TTworkbench 28 package contains an OpenJDK 12 installation in the "jdk" subfolder of the TTworkbench installation folder
