Maven: missing net.sf.json-lib
Looking at the maven-central repo, you need to specify a classifier for this dependency.
Either jdk13 or jdk15, like this:
<dependency>
<groupId>net.sf.json-lib</groupId>
<artifactId>json-lib</artifactId>
<version>2.4</version>
<classifier>jdk15</classifier>
</dependency>
For gradle as sample
compile 'net.sf.json-lib:json-lib:2.4:jdk15'
OR
compile group: 'net.sf.json-lib', name: 'json-lib', version: '2.4', classifier: 'jdk15'
I searched for more classifier's could not find anything other than jdk15 (don't go looking or jdk16 or jdk17)
