Hello,

I try to learn myself Java/Angular, Springboot with Mariadb.
Therfore I follow some tutorial from the internet.

I can start my project as springboot application and it is running the server.
The only thing is at the turorial/example, if he run the application, a table is created in the database and this is not happening when I run the project/application.

If I open the pom.xml file I get the error:
"An internal error occurred during: "Loading referenced grammars". org/eclipse/jdt/core/IElementChangedListener"

I don't know if this is the reason why not the table with his fields is created, but I want to solve this error at least first.

I have removed the history of Eclipse (help--> about Eclipse --> Installation Details/Installation History). I have read this on the internet. I didn't remove the 'Current Installation'.

What else can I do, or what is the reason of this error?

I hope that someonen can help me further and/or help me out what to do to solve this issue.

Is there an entry in the Error Log View with a stack trace? Which release of Eclipse is this?

I'm working with Eclipse 2020-06 on fedora Linux, but the Eclipse which I have is from the Eclipse.org.

No, there is not a stack trace in my console. I can start this project as springboot app
At 'problems' I see this:
Quote:

Duplicating managed version 2.7.0 for mariadb-java-client | pom.xml | /Springboot-backend line 40 | Maven pom Loading Problem


It's about this in the pom.xml file, the version tag:
<dependency>
	<groupId>org.mariadb.jdbc</groupId>
	<artifactId>mariadb-java-client</artifactId>
        <version>2.7.0</version>  <!-- Duplicating managed version 2.7.0 for mariadb-java-client -->
</dependency>


**** EDIT ****
I have changed eclipse.ini, so that I can start up as sudo. Now I get this:
Quote:
No editor descriptor for id org.eclipse.m2e.editor.MavenPomEditor


And then the details are:

***** EDIT 2 *****
I have succeeded the update of the eclipse platform from 2020-06 to 2020-09., can that be the reason of my earlier mentioned error "No editor descriptor for id org.eclipse.m2e.editor.MavenPomEditor"?

Ok, I don't know exactly how it is fixed now, but as said I have updated the eclipse version from 2020-06 --> 2020-09.

After the first start I got the question: "It seems that this is the first time that start Eclipse... would take the plugins from the earlier version..." (something like this) Yes/Exit. Of have choosen Yes, but not all plugins are installed again like " m2e - Maven Integration for Eclipse". After installing the plugin again te error is "No editor descriptor for id org.eclipse.m2e.editor.MavenPomEditor" as well the error "An internal error occurred during: "Loading referenced grammars". org/eclipse/jdt/core/IElementChangedListener" !!!

I saw just that my Servers view was also lost (Tomcat). I have Restart Eclipse after installing the plugin just mentioned and now it is back??

I'm 'new' to Eclipse and I try to analyse what do I'm wrong? What is the reason that I update Eclipse running under sudo and now I'm using running under an user which administrator.... This hard to understand for me.

But for now, the issue is solved so far...
