Apache Karaf with Java 1.7

Question

I have joined a new project that uses Java 1.7. They are also using Apache Karaf .

My problem is Apache Karaf only works with Java 1.8+. The project is old, and other developers are using an older version of Apache Karaf, which is no longer available.

The only prerequisite to start with Karaf is a Java SE 8 / 9 / 10 / 11 environment to run.

Question

Seeing that I can't upgrade from Java 1.7, does anyone know where I can get a version of Apache Karaf that works with Java 1.7? Or how I can get Apache Karaf to work with Java 1.7?

Thank you

Most Apache Karaf builds are still available from Maven Central.

Apache Karaf v4.0.10 should support Java 7 for you.
