Maybe there was a network problem, because that exists as seen in a browser

https://download.eclipse.org/releases/neon/
https://download.eclipse.org/justj/?file=releases/neon

Maybe the problem is that http redirects to https and something is not handling the redirection properly. Try using https instead.

You are right, repository exists, but not https://download.eclipse.org/releases/neon/compositeContent.xml

No but https://download.eclipse.org/releases/neon/compositeContent.jar exists and p2 tries this first, then the *.xml version and when both fail, the error message only mentions the *.xml name.

Thank you for your answers. So how to fix it? Why maven doesn't use compositeContent.jar?

I think it's just network problems. I don't see anything broken. I have suggested using https. Have you tried that?

You can use this to explore what's physically present on the server:

https://download.eclipse.org/justj/?file=releases/neon

You could look in the composite jar to see what's there:
<?xml version='1.0' encoding='UTF-8'?>
<?compositeMetadataRepository version='1.0.0'?>
<repository name='Eclipse Repository'  type='org.eclipse.equinox.internal.p2.metadata.repository.CompositeMetadataRepository' version='1.0.0'>
  <properties size='3'>
    <property name='p2.timestamp' value='1313779613118'/>
    <property name='p2.compressed' value='true'/>
    <property name='p2.atomic.composite.loading' value='true'/>
  </properties>
  <children size='7'>
    <child location='../../technology/epp/packages/neon/'/>
    <child location='201606221000' />
    <child location='201609281000' />
    <child location='201610111000' />
    <child location='201612211000' />
    <child location='201703231000' />
    <child location='201705151400' />
  </children>
</repository>


And you can see then that this repository is also available:

https://download.eclipse.org/releases/neon/201705151400/

As long as your reference things that are present, best using https, there should be no problem...

Looks like problem was with Java version. I finally build app with Java 1.8 but not with Java 19.
