How should I choose a version

[FIREWOODCUT]

Hello! Due to the unique nature of the project, I need to lower the Java compiled version from 8 to 7, which has caused some issues. At first, I thought it was a local environmental issue, but later I created an empty project that could be successfully compiled. As I gradually add dependencies, I try to reduce the versions of various dependencies until 'mq jms spring root starter' and find that it seems that all versions do not support Java 7. What should I do?

Quite apart from this particular package, which has always required a minimum of Java 8

• Spring Boot 2 requires Java 8
• MQ 9.1 onwards requires Java 8

So you might be able to cobble together variants of very old unsupported components, perhaps modifying or recompiling some parts of it yourself. But otherwise, you'll be out of luck.

Okay, thank you for your reply.
