run ant with different jdk

[Tom Eicher <te...@teicher.net>]

Hello,

so NB19 needs Java11+ to run, which is fine.

But (for now) I need to run my ant task with Java8,
but it seems ant is always launched within the JVM
that runs NB.

Testing, with Java8, on command line "ant dist" builds my ear,
whereas with Java11 I get errors like
cannot find symbol javax.annotation.Generated
which is probably expected.

Running in NB19, I get the very same error, and no setting I
found would change this behaviour.

Basically, I have the very same question like this one:
https://stackoverflow.com/questions/70036683/how-to-change-java-for-ant-in-netbeans
and none of the solutions works.

Any 5ct?

Thanks, Cheers, Tom.

Alternatively, did you tried adding the `javax.annotation-api` JAR file 
to the libs used by Ant [1]?

Hello,
You might want to tweak which ant is used.
In the options>Java>Ant (first tab) you can set the ant home to any
directory you want.
You could adapt or wrap the ant script (depending on your OS), By setting
the JAVA_HOME environment variable to the jdk of your liking.

A strategy is to rename the ant script chosen by your OS (e.g. ant under
Linux or ant.cmd on Windows) to something like ant-orig[.cmd]
Then create a cmd or shell script with the contents (linux example shown)
-----
#!/bin/bash
ANT_HOME=.... (fill in)
export JAVA_HOME=... (fill in)
$ANT_HOME/bin/ant-orig "$@"

Met vriendelijke groet,
