Eclipse: Oxygen and m2e plugin don't get along?

[oliv3r]

Hello,

It looks like the Oxygen Eclipse plugin doesn't get along with the m2e ("Maven Integration for Eclipse", http://www.eclipse.org/m2e/) plugin.

I experience the following problem, when the m2e plugin is installed: After I open a XSD document and toggle between the tabs "Text" and "Design" I get an error message:

"Could not open the document in mode 'Design': null" (and "Could not open the document in mode 'Text': null" respectively).

In Eclipse's error log I see:

Code: Select all

"Unhandled event loop exception"

This happens in both the "Java" and the "Oxygen XML" perspectives.

Workarounds I found:

• Closing the "Outline" view in all perspectives (and then restarting Eclipse) solves the problem.
• Uninstall m2e

Has anyone else observed this behavior?

My setup:

• Eclipse: 3.7 (Indigo JEE release and 3.7.1 M20110810-0800)
• Oxygen: com.oxygenxml.editor_12.2.0.v2011080114.zip
• m2e - Maven Integration for Eclipse: 1.0.0.20110607-2117
• Java: 1.6.0u24

Yours,
Oliver

Dear Oliver,

Thanks for the feedback.

Eclipse 7 had some changes in the way it interacts with plugins which manifested in problems like the one you reported.

Oxygen 13 which should appear in a couple of weeks should fix these problems.

Hello Radu,

This is good news, thanks!

I just bought the Academic version of Oxygen 12.2. Do you know if I'm eligible to get Oxygen 13 when it comes out for free? Or will I have to buy an update?

Regards,
Oliver

Hi Oliver,

An Academic license key comes with the SMP (Support + Maintainance Pack) package included so yes, you will have free use of Oxygen 13 when it comes out.

Regards,
Radu

Hi,

We've made a few fixes that should prevent this in the latest build of 12.2, 2011082411 and also in v13.

You can find v12 in our software archive:
http://www.oxygenxml.com/software_archive.html

v13 is on the regular download page:
http://www.oxygenxml.com/download.html

Please let us know if you encounter further difficulties with the new version/build.

Regards,
Adrian

Hi Adrian,

I just installed the v13 Eclipse plugin. Works like a charm so far

Thank you very much,
Oliver
