Eclipse AEM Plugin not working

[LKAemNewbie]

Hi,

I am a newbie to AEM and installed AEM dev tool for eclipse whose version is below.

Eclipse IDE for Java Developers

Version: 2023-06 (4.28.0)
Build id: 20230608-1333

Added 2022-09 as well.

Post installation, when trying to create new project in eclipse, after selecting AEM Sample Multi module Project it isn't going to next screen where we would enter archetype details ect. Instead it is stuck on new project screen and below are the error details from error log. Please suggest how to resolve this.

An error has occurred. See error log for more details.

org/eclipse/m2e/core/internal/index/IndexListener

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

java.lang.NoClassDefFoundError: org/eclipse/m2e/core/internal/index/IndexListener

Caused by: java.lang.ClassNotFoundException: org.eclipse.m2e.core.internal.index.IndexListener cannot be found by org.apache.sling.ide.eclipse-m2e-ui_1.2.2

Hi @LKAemNewbie 
Please use CMD to generate AEM project with correct archtype

Thank you for responding. I tried that way.. build was successful in command prompt and while importing or updating maven project in eclipse it gave below error. 

An internal error occurred during: "Updating Maven Project".

java.lang.NoSuchMethodError: 'org.eclipse.core.resources.IProject org.eclipse.m2e.core.project.configurator.ProjectConfigurationRequest.getProject()'

Make sure your Eclipse can read MAVEN, meaning that your MAVEN is installed globally and you have an environment variable. It looks like if you could generate the project via CMD then the IDE is the problem, please check this thread which explains how to use eclipse with AEM projects:

Hope this helps

Hi,
I am still experiencing the exact same original issue of this post. May I ask if there is thorough solution?

Notes: using maven cmd can do the work but i believe the reported error comes with other errors / inconveniences in the IDE as well, for example: there is no "import from server" option when you want to import content from Author back to IDE.

TIA
