Hi, 

Hopefully this is the right forum for such a question.

We're trying to use JZOS from maven-central (https://mvnrepository.com/artifact/com.ibm.jzos/ibm.jzos) for compilation purposes.

The jar seems to have been compiled using Java 11 which prevents us from using it in Java 8 applications.

Can a Java 8 compiled jar be published as well?

Thanks,

Roded

Thanks for the reply Min Su Cho.

We're using Gradle to compile a project which uses a Java 8 toolchain and which has JZOS as a compileOnly dependency the following error is reported:

import com.ibm.jzos.ZFile;
                   ^
  bad class file: /Users/rbahat/.gradle/caches/modules-2/files-2.1/com.ibm.jzos/ibm.jzos/3.1.3.1/93747a6959750874af749886c1cb5e0b38eb4059/ibm.jzos-3.1.3.1.jar(com/ibm/jzos/ZFile.class)
    class file has wrong version 55.0, should be 52.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.

This is a error coming from Java8's javac.

And it does seem like the JZOS classes have been compiled with 55.

Please advise.

Thanks

Thank you Roded Bahat for posting the error message.

I have gone through the Gradle build from my end and other build tools. We don't officially support Gradle and only encourage using Maven and manual importing at the moment. What I can suggest for now is to use other build tools.

Please let me know if the issue persists even after you change the build tool.

Thank you

That's very disappointing Kevin.

Using a different build tool is definitely not an option. And I'm not sure what you mean by "manual importing". We would like to be able to compile against JZOS just like any other jar avaliable in maven central.

This isn't really a matter of officially supporting Gradle vs Maven, but rather, just providing a JZOS jar which has been compiled using Java 8.

Can't IBM provide a JZOS jar which has been compiled with Java 8? This could even be an older version of JZOS if the current version requires Java 11 language features.

Thanks.

The team has been looking into a v8 of JZOS jar to Maven. This is being considered in prioritization backlog.

Hello Srinivasa,

We released JZOS on Maven for Java 8.

Here is the IBM documentation (https://www.ibm.com/docs/en/sdk-java-technology/8?topic=components-managing-jzos-dependencies-by-using-maven) for Java 8 JZOS Maven.

We're looking to adjust and align artifact naming for JZOS on Maven, so they provide a better UX for our users.
