  • Extracted javaagent-extension-api from tooling & spi (#2879)
    • You no longer have to depend on the javaagent-tooling module to implement custom instrumentations: a new javaagent-extension-api module was introduced, containing all the necessary instrumentation classes and interfaces;
    • InstrumentationModule and TypeInstrumentation were moved to the io.opentelemetry.javaagent.extension.instrumentation package;
    • AgentElementMatchers, ClassLoaderMatcher and NameMatchers were moved to the io.opentelemetry.javaagent.extension.matcher package;
    • A new SPI AgentExtension was introduced: it replaces ByteBuddyAgentCustomizer;
    • InstrumentationModule#getOrder() was renamed to order();
    • InstrumentationModule#additionalHelperClassNames() has been removed; use isHelperClass(String) instead if you use the muzzle compile plugin. If you're not using muzzle, you can override getMuzzleHelperClassNames() directly instead;
    • InstrumentationModule#getAllHelperClassNames() has been removed; you can call getMuzzleHelperClassNames() to retrieve all helper class names instead.
