Is it possible with oomph to have the JRE copied inside the eclipse installation in the jre subfolder (i.e folder eclipse\jre) so that it will be included in each installation?

It's possible in principle, but there are some details that would need attention. E.g., not generating a -vm entry in the eclipse.ini. Also, while a Resource Copy task can be used to unzip a remote resource (zip) into a local folder, on Mac and Linux there is the issue of setting the executable bits for the JRE to be properly functional.

Note that we have approval to redistribute OpenJDK so some work will be done in this area soon:

Hi,
I am also trying to do bundled JRE and I would like to ask you how can I get rid off predefined -vm <java_path> in eclipse.ini.

I succesfully copied resources into eclipse install destination. I add -vm budled_java_path into Eclipse.ini.

But I do have predefined init task during setup which adds my localy installed java into Eclipse.ini.

See the attachted picture:
- yellow marked lines are somehome predefined and I do not know how to get rid of them
- red maked is my task which should be the only one there.

Did you create the task exactly like this?

<?xml version="1.0" encoding="UTF-8"?>
<setup:EclipseIniTask
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0"
    option="-vm"
    value="jre/bin"/>

It's important to separate the two parts into the option/value so that this -vm task overrides the other -vm task.

I used the UI editor instead of XML. It looks like this in my .setup file:

<setupTask
          xsi:type="setup:EclipseIniTask"
          option="-vm "
          value="jre/bin"/>

Its hard to now the syntax without documentation :( But I will try it your way :)

Note that in your original version you had a space after -vm whereas the correct version does not have that.

I do have another question. I am using Resource Copy task to copy unzipped jre folder into installed eclipse instance using as target path: ${installation.location/}${installation.relativeProductFolder}

it works as it should... sort of.

It creates the jre folder in target path, copy some of files into it, but in the comparation of source/target file count, filecounts are not the same, in target folder are 100-ish files missing.

Any ideas, how to solve it? :(

I don't have a theory for that. You could create a development environment using https://www.eclipse.org/setups/installer/?url=http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/configurations/OomphConfiguration.setup&show=true and then try running the task in debug mode with a breakpoint in org.eclipse.oomph.setup.impl.ResourceCopyTaskImpl.perform(SetupTaskContext) to see what's happening. You could debug the launched installer or for quick testing, you could launch the "IDE" launcher in debug mode, use Navigate -> Open Setup -> Workspace, copy your resource copy task into the Workspace (with a target location that works for testing purposes), and then use Help -> Perform Setup Tasks to run it.

Thank you for your tip, I already use debugging. :) I will try to debug this task and hopefully it will get me on to something.

I found out the root cause of my trouble. The problem was the task priorities. I setup the (copy destination) java bundle path into Eclipse.ini. But the Eclipse.ini task run earlier than copy task. Once I setup the predecessors for Eclipse.ini task, it started working perfectly.
