Java 8 is not supported

[yegor256]

Currently, in the CI we only support Java 11+. How about Java 8? Looks like it's still alive. Would be great to support it too.

@yegor256 thanks for the report, here is a feedback:

Problems

• The bug report's title is currently phrased as a question, which doesn't clearly define the issue.
• The problem description is missing specific details like the error message or the observed behavior when attempting to use Java 8.
• The report fails to provide steps that could be followed to reproduce the issue, which are crucial for both understanding and resolving the problem.

I would recommend making the title more specific, such as "CI System Lacks Support for Java 8".

Please fix the bug report in order it to get resolved faster.

@c71n93 maybe you can try to help?

[c71n93]

@yegor256 yes, I will try

@yegor256 I faced with such problems while trying to use java 8 for build. Both problems are due to the fact that some dependencies are compiled under java 11 (class file version 55), which does not allow to use runtime java 8 (class file version 52).

Here log for error with qulice-maven-plugin (you can see it in this job too):

As far as I understand, the only way to build and run eo under java 8 is to downgrade all dependencies to a version where the jar file in maven-central will be compiled under java 8.

For example, for the antlr4-maven-plugin maximum version that was compiled with java 8 is 4.9.3.

@yegor256 The question is: do we really want to downgrade dependencies versions to be able to compile and run under java 8? I couldn't find any other options.

[yegor256]

@c71n93 maybe we can have so called "conditional" compilation in our pom.xml: an additional profile that is activated when Java version is 8. In this profile, all dependencies will have different versions.

[c71n93]

@yegor256 yeah, maybe. I will try.

[volodya-lombrozo]

@yegor256 @c71n93 It's important issue for me too. I use print goal to translate xmir files into eo files:

<plugin>
  <groupId>org.eolang</groupId>
  <artifactId>eo-maven-plugin</artifactId>
  <version>0.38.1</version>
  <executions>
    <execution>
      <id>convert-xmir-to-eo</id>
      <phase>process-classes</phase>
      <goals>
        <goal>print</goal>
      </goals>
      <configuration>
        <printSourcesDir>${project.build.directory}/generated-sources/jeo-xmir</printSourcesDir>
        <printOutputDir>${project.build.directory}/generated-sources/jeo-eo</printOutputDir>
      </configuration>
    </execution>
  </executions>
</plugin>

And on Java 8 I get the following error:

[ERROR] Failed to execute goal org.eolang:eo-maven-plugin:0.38.1:print (convert-xmir-to-eo) on project jeo-it: 'org.eolang.maven.PrintMojo@3b2553d9' execution failed: java.io.UncheckedIOException: java.io.IOException: java.util.concurrent.ExecutionException: java.lang.NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer; -> [Help 1]
