I have to process JSON response in a Java 1.6 project without any library manager (can't use Maven). So, in order to do so, I chose Jackson 2.6.7 (https://github.com/FasterXML/jackson/wiki/Jackson-Release-2.6.7.x) that can be used with Java 6.
I downloaded core, annotations and databind jars from here https://repo1.maven.org/maven2/com/fasterxml/jackson/core/jackson-core/2.6.7/ but, when I import those jars into my project and start it I get "Unsupported major.minor version 52.0".
I thought those jars were built with Java 8, so I downloaded the source jars, unpacked them, compiled and built the jar again di Java 6: same result.
It feels like I'm missing something, how do can I build those libraries to run on a Java 6 project?
