Why JRE and not ANT JDK settings? [message #1707734]

Eclipse for RCP and RAP Developers
Version: Mars Release (4.5.0)
Build id: 20150621-1200

While updating this e(fx)clipse tutorial I am getting stuck. The current draft of the updated tutorial is here. The
"Generate ant build.xml and run" step produces the error seen in the embedded screen capture.

index.php/fa/23185/0/

I had to add a JAVA_HOME environment variable to my OS and set it to the JDK. Then I set the JDK in the eclipse.ini file too. But I am still having issues with ant.

What do I check next?

The ant-launch is using the projects JRE System Library of the project
which is in your case only a JRE. The best solution is to teach Eclipse
about the JDK and remove the JRE.

Sorry, but I don't understand the answer.

Quote:

In my case the preference for ANT points to a JDK \...\jdk1.8.0_25\lib\tools.jar
Preferences -> Ant -> Runtime -> Global Entries. So why is the Java FX build using the JRE for the project and not using the preferences for ANT, when doing a build, as shown? What am I missing here?

Why do I need to change anything with the JRE when the preferences for ANT point to the correct JDK?

It means, you are looking in the global preferences, not in the project properties. And you should configure a JDK to the Installed JREs and connect the appropriate Execution Environment.

Paul,

This is wonderful work! - I hope this will save many others a lot of time.

I often regret that I have not enough time to keep the documentation at
a level that really helps the beginners!
