I've used the newest Eclipse IDE for Java EE developers (2024-9), but still getting the following problem on pom.xml when checking out the validator project:

Failed to execute mojo org.apache.maven.plugins:maven-resources-plugin:3.3.1:resources {execution: default-resources} (org.apache.maven.plugins:maven-resources-plugin:3.3.1:resources:default-resources:process-resources)

The complete stack trcace:

I've found the file name 'app-info.properties' on the stack trace and searched for the root cause ('java.nio.charset.MalformedInputException: Input length = 1'). I've found some hints that the encoding of the file can cause this error.
After converting the encoding of the file from ANSI to UTF-8 (using Notepad++) on my local cloned git repsitory and Eclipse restart / project cleanup, the eror gone away...
