Make TM4E core lib accessible via Maven

[mickaelistria]

Since org.eclipse.tm4e.core is Eclipse-independent and can be used in plain Java context, it would be great to publish it to Nexus: https://bugs.eclipse.org/bugs/show_bug.cgi?id=514346

Hello, is publishing to Maven still planned or abandoned?
If abandoned, I will fork and publish for my usage.

[mickaelistria]

If you can contribute to make it happen, it would be very welcome!

[mickaelistria]

If you mvn install from source code locally, can you then consume the org.eclipse.tm4e.core artifact as expected?

[exoego]

I am happy to contribute !!

Well, I could import it as

<dependency>
  <groupId>org.eclipse</groupId>
  <artifactId>org.eclipse.tm4e.core</artifactId>
  <vesion>0.3.4-SNAPSHOT</version>
</dependency>

(actually I used sbt instead of mvn, so "org.eclipse" % "org.eclipse.tm4e.core" % "0.3.4-SNAPSHOT" is an actual identifier I used)

and then Java code

import org.eclipse.tm4e.core.registry.Registry;

is compilable.
The groupId and artifactId is a bit weird for me, but it works !!

So... how can I contribute to make this issue forward ?

Ah, it seems that TM4E does not support JDK 11... ???
I got this error when running a code using org.eclipse.tm4e.core.registry.Registry.

Here is a suggestion:
You work on having it published on a local instance of Nexus of yours, you submit PRs for necessary change, if any. Once it's working for you, you share your configuration and we work on adapting it to Eclipse Nexus instance (at repository.eclipse.org).

Ah, it seems that TM4E does not support JDK 11... ???

It does work with JDK 11, at least as an Eclipse IDE plugin.

I got this error when running a code using org.eclipse.tm4e.core.registry.Registry.

I don't see anywhere in the stack anything related to TM4E. Can you please share a full stack highlighting what operation of tm4e triggers that?

[exoego]

Ah, sorry, it was my mistake on build configuration.
Actually it worked on JDK 11.
I will try to publish to my private Nexus.

Hello,

I'm also looking for this on Maven central.

I found this, but it's quite old, and I'd rather work from "org.eclipse" group id.

	<dependency>
	  <groupId>org.netbeans.external</groupId>
	  <artifactId>org.eclipse.tm4e.core_0.2.0.201809031154</artifactId>
	  <version>RELEASE110</version>
	</dependency>

To be honest, I don't think publishing to plain Maven is a functionality I'm going to work on soon as it's not a priority to me. However, we'll totally welcome contributions that go into that direction.
