There are 3 programs which provide 'java'.

I am using java 17 to build the service and making use nexus oss 3.30.0.1. The angular package.json has below properties to pull a specic version of jar from nexus. "verigon-sharedlib": "2.16.2712", Irrespective of the fact hardcoded version given to pull jars from nexus its not doing so. But after some time interval ( around 120mins), if we try to build the package again it picks up latest and mentioned version. So there is basically a dalay while it picks up mentioned/latest jar from nexus.
