This discussion was created from the release CDT 12.2.0 for Eclipse 2025-09.

@jonahgraham : First of all thanks for the new release.

However I have a problem with this update.

I would like to integrate the TM Terminal in an RCP. This recipe cited here worked until 2025-06:

https://www.eclipse.org/lists/tm-dev/msg01128.html

Has the API changed? Is there a new example available how to open the TM Terminal programmatically?

Another question. Is it also possible to send shell commands to an active shell?

[jonahgraham]

Has the API changed?

Pretty much only the namespace has changed as the Eclipse Platform project has adopted the terminal. Generally org.eclipse.tm.terminal has been renamed org.eclipse.terminal and you should consume the feature from Eclipse Platform (or SimRel) directly.

I have added the missing N&N entry in CDT.

---

Is it also possible to send shell commands to an active shell?

I think what you want is pasteString

Eclipse Copilot has not updated to the new namespace, but they recently contributed code that does this, so looking at RunInTerminal may be a useful starting point, in particular executeCommand.

---

I hope that unblocks you - thanks for asking! Let us know how you get on with the above and feel free to ask more questions.

[Bio7]

Thanks for the useful links and information.

The 'RunInTerminal' example looks promising.

[Bio7]

One additional question. I can't resolve the "TerminalServiceFactory":

ITerminalService terminal = TerminalServiceFactory.getService();
if (terminal != null) terminal.openConsole(properties, done);

Has this changed? This is also used in the RunInTerminal example.

[jonahgraham]

@Bio7 I don't know the "correct" answer, but yes TerminalServiceFactory was removed. See eclipse-platform/eclipse.platform#2157 where I asked the new maintainers what they thought.

[Bio7]

@jonahgraham Thanks for your answer and your help. I will try if the suggestions work.
