Broken build (Source option 6 is no longer supported. Use 7 or later.) #824

Open hendrikebbers opened 1 year ago

hendrikebbers commented 1 year ago

When I just call ./mvnw verify in the repo the build ends with the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project simpleclient_tracer_common: Compilation failure: Compilation failure:

The current java_client version is still backwards compatible with Java 6. You need JDK <= 11 to compile it from source, because Java compilers later than 11 dropped support for Java 6 output.

I am currently working on an 1.0 release with a major refactoring (to support Prometheus native histograms). I think with that release we'll drop Java 6 support and use Java 8 as the baseline.

Note that this is only for compiling client_java from source. At runtime you can use client_java with any Java version >= 6, there are no compatibility issues at runtime.

I created a PR to add the info to the readme https://github.com/prometheus/client_java/pull/830

Next to this the build is still not working since simpleclient_caffeine depends on https://github.com/ben-manes/caffeine version 3.X that only supports Java 11+

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project simpleclient_caffeine: Compilation failure

With Java 11 the project should build successfully.
