Error while packaging with Jdk 1.5

[anandwali]

Hi,

I am getting this error while building with Jdk 1.5. Is it not compatible?

Hi,

Spring boot requires at least java6. I am afraid this will not work with your current setup. Any reason why you could not upgrade to a more recent Java version?

Thanks!

Hello, Thanks for answering my query. I found it the hard way that it does
not work on Java5.

I am in customer environment, where production servers are on Java 5,
changing it would be a governance blocker at this stage.

Hope you understand..

BTW, is there a way to find which release of spring works on which which
version of Java?

Thanks, Anand

"Which release of Spring..." is a bit of an open-ended question, since "Spring" can mean different things to different people. This is the issue tracker for Spring Boot, so I'll answer for that project: we require Java 1.6 for all Spring Boot releases to date (as stated in the docs here).

The answer for other projects can generally be found in their release notes.

Thanks Dave,

I am looking to use Spring-batch with spring boot on Jdk5. As Spring boot
doesn't support jdk5, I wanted to make sure which version of spring-batch
is released with jdk5 compatability or do I need to take a maven build on
jdk5? Or do I assume all works on jdk 5 as doc says spring-batch 2.x is
targeting jdk5?

Thanks, Anand

If the Spring Batch docs say 1.5 then it's 1.5, but that's not going to work with Boot.

Spring Boot is builds on new features introduced in Spring Framework 4.0, since this needs Java 6 there is zero chance of getting Spring Boot working with Java 5.

I would strongly recommend that you look at upgrading from Java 5 if at all possible.
