Error creating Liferay plugin project

[Robert Holt, geändert vor 9 Jahren.]

Hello,

I have been following the developer's guide found here:
https://www.liferay.com/documentation/liferay-portal/6.2/development/-/ai/developing-apps-with-liferay-ide-liferay-portal-6-2-dev-guide-02-en

When I go to create a new liferay plugin project I get the following error:

Hi,

Same issue here - did you solve it ?

Thanx

Mathieu.

[Robert Holt, geändert vor 9 Jahren.]

Glad to hear I'm not the only one. No, I have been trying things for days now but I cannot figure out what is wrong.

[Gregory Amerson, geändert vor 9 Jahren.]

Hey guys,

This is a known issue: https://issues.liferay.com/browse/IDE-1537

[Robert Holt, geändert vor 9 Jahren.]

The title of the issue is "Unable to create projects when jre8 is default jre", but I am getting the exact same error when using jre7.

[Robert Holt, geändert vor 9 Jahren.]

I have solved the problem. By default my eclipse compiler compliance level was set to 1.4. Changing it to 1.7 did the job.

Thanks again,
Rob

Hi

Default compliance level is set to 1.6 for me, but still the same issue.

[Gregory Amerson, geändert vor 9 Jahren.]

Hey guys, for those of you still have problems could you try the most recent nightly build? See if it helps any:

[Mathieu Hicauber, geändert vor 9 Jahren.]

Thanks, we'll give it a go next week.

[Gregory Amerson, geändert vor 9 Jahren.]

We pushed another build today that also fixed an issue related to the "One or more constraints have not been satisfied." issue. I hope this fixes things for you.

Hello Tania,

We would like to help, but you will have to give us some more information to go on. What exact version did you install? what is your portal and sdk version (or are you using maven?) and then want exactly is the error that you encountered?

What is your default JRE in eclipse ? Window > Prefs > Java > Installed JRES?

[John Voltaire Maximo, geändert vor 8 Jahren.]

the preselected one was 1.8,,,, I looked into other posts and change my preference to 1.6 instead...
that worked for me,, thanks anyway for answering sir
