Note: Eclipse Adoptium Temurin Runtime Version jdk-17.0.17+10, jdk-21.0.9+10, IBM Semeru Runtime Version jdk-17.0.17+10, jdk-21.0.9+10, OpenJDK 17 and OpenJDK 21 were used for verifying these instructions.

2. Set environment variables

export JAVA_HOME=<path to java>
export PATH=$JAVA_HOME/bin:$PATH

3. Use Camel jars

To use the Camel binary in your Apache Maven pom.xml, import the Camel Bill of Materials (BOM) and then include the camel-core and any other components needed as mentioned here. There are also few examples available for reference.

Note: Apache Component references provides various references that offers services for messaging, sending data, notifications and various other services that can not only resolve easy messaging and transferring data but also provide securing of data. However few components such as Deep Java Library and Kudu are not supported on s390x. Java Flight Recorder, GraalVM Polyglot are not available in IBM Semeru Runtime (OpenJ9).

If you want to build Camel from source, refer official documentation. In this documentation mvn clean install runs all the unit tests.
