Java – why do I get Maven error: “unable to determine whether resource x exists in http://maven.glassfish.org/content/groups/glassfish ”?
Whenever we execute our website target in maven, we get a long list of dependency related errors in the console log The error appears to have been generated in the creation section of the generated dependency report When directed http://maven.glassfish.org/content/groups/glassfish When the repository checks resources, it seems that all errors will be generated (there's a strange JavaFX error there, but we don't have to worry about it now) the build did succeed

I did some research and it seems that the repository URL listed is correct I wonder if it could be an error in our dependency reporting plug-in? Uncertain, welcome suggestions or guesses
Edit: publish detailed console output for one of the following errors:

Solution
You will need to simply add < dependency locations. enabled> false< /dependency. locations. enabled\u0026gt; To disable dependency location checking; In your POM The attribute part of XML is as follows:
<properties> ... <dependency.locations.enabled>false</dependency.locations.enabled> </properties>
For more details, see the parameter dependencylocationsenabled, which defaults to true
