Hi,

after the upgrade on CI 8 it seems that the m2e plugin started to return the following exception.
The problem here is that I have in MyEclipse, after the Maven Update project feature the popup with the NullPointException alert that is very annoying.

I have to use Maven from bash because for some project I can’t

The strange thing is that for any Maven project I have a similar exception and I don’t understand what is the real cause. From a Java point of view I should have any configuration correctly set.

Could you please support me?
Thank you.

It seems that the problem is related to facets, I can’t see the dialog for managing facets it is returning a black window with a NullPointerException:

Piergiorgio,

You mentioned both CI 8 and CI 9 in your title (CI 9 was released on Friday). Can you clarify what version you were on before you started experiencing issues – and did you run into this problem with both CI 8 and CI 9?

Can you zip-up the .settings folder as well as the .project folder of your project and send it to us? We’ll take a look right away and see if your project metadata is bad, causing this problem. Apologies for the inconvenience caused.

Hi Brian,

You mentioned both CI 8 and CI 9 in your title (CI 9 was released on Friday). Can you clarify what version you were on before you started experiencing issues – and did you run into this problem with both CI 8 and CI 9?

I started to have some issues from CI8 but it was usable, starting from CI9 I can’t use it.
I have attached a zip file with .settings and .project.

Thank you for your support.

Piergiorgio,

What version of MyEclipse are you coming from – in which this project worked fine? It would appear that your project does not have enough metadata for Maven to work correctly – while the facet nature is present, the faceted project metadata is mostly missing from this project – so it looks like migration to a recent version was incorrectly performed. Did you modify the project properties or metadata yourself?

Can you see your project listed in the Workspace Migration view? Window > Show View > General > Workspace Migration. If so, please refresh the view and go through the migration steps. From the error log you attached before, there’s a chance it isn’t visible, in which case we’ll give you some manual steps to perform.

[Piergiorgio Lucidi]

What version of MyEclipse are you coming from – in which this project worked fine?

MyEclipse CI 7 worked very well, starting from CI 8 I saw problems.

Did you modify the project properties or metadata yourself?

No.

Can you see your project listed in the Workspace Migration view? Window > Show View > General > Workspace Migration.

The view is empty, I didn’t see any project to migrate.

[support-swapna]

Piergiorgio,

Attached is the zip containing the missing facet metadata files which you can copy into your project’s .settings folder.

Shut down MyEclipse and in the file system explorer unzip the contents of the attached zip into your project’s .settings folder (leave the rest of files as it is). Once done, start MyEclipse and check if the problem still exists.

If you are still seeing the issue, please clarify if you are seeing the problem in all the maven projects in the workspace. If possible, switch to a new workspace, check if the issue persists and send us the .log file located at workspace dir/.metadata/.log for further investigation.

Apologies for inconvenience caused. Please let us know how it works for you.

Unfortunately the problem is not solved also in the latest release, anyway you could take a look at the attached log snippet.

[support-swapna]

Piergiorgio,

Sorry that you are still seeing this problem.

1. Can you please clarify if you have copied the facet metadata files I sent in my previous response?
2. In the latest MyEclipse 2019.4.0, do you see this problem if you create a new maven project (maven-archetype-webapp archetype)?
3. If the issue is only with one particular project, then please share with us the zipped project (excluding the source files in case they are private), including the .settings folder, .classpath,.project files and the pom.xml.
4. Please switch to a new workspace, import the troubled project, replicate the problem and share with us the full workspace log file which is located at workspace dir/.metadata/.log to help us get the full list of errors logged. If you are seeing the issue with a new project as well, then instead of importing the older project, create a new one and share the .log file (save the .log as .txt and attach it).

Apologies for inconvenience caused.
