In order to build and test this whole repository you need JDK 11+. Some instrumentations and tests may put constraints on which java versions they support. See Running the tests for more details.
For developers testing code changes before a release is complete, there are
snapshot builds of the main branch. They are available from
the Sonatype OSS snapshots repository at https://oss.sonatype.org/content/repositories/snapshots/ (browse)
Build using Java 11:
java -version./gradlew assembleand then you can find the java agent artifact at
javaagent/build/libs/opentelemetry-javaagent-<version>.jar.
