Generate DSL Classes
Run the v2 compiler (ANTLR4 + Javassist) to generate bytecode classes from DSL scripts and dump .class files to disk for inspection.
Commands by argument
mal — MAL expression classes
./mvnw test -pl oap-server/analyzer/dsl-scripts-test \
-Dtest=MALExpressionExecutionTest -DfailIfNoTests=false -Dcheckstyle.skip
Output location: oap-server/analyzer/dsl-scripts-test/src/test/resources/scripts/mal/**/*.generated-classes/
oal — OAL metrics/dispatcher/builder classes
./mvnw test -pl oap-server/oal-rt \
-Dtest=RuntimeOALGenerationTest -DfailIfNoTests=false -Dcheckstyle.skip
Output location: oap-server/oal-rt/target/test-classes/metrics/, metrics/builder/, dispatcher/
lal — LAL filter/extractor classes
./mvnw test -pl oap-server/analyzer/dsl-scripts-test \
-Dtest=LALExpressionExecutionTest -DfailIfNoTests=false -Dcheckstyle.skip
Output location: oap-server/analyzer/dsl-scripts-test/src/test/resources/scripts/lal/**/*.generated-classes/
hierarchy — Hierarchy rule classes
./mvnw test -pl oap-server/analyzer/dsl-scripts-test \
-Dtest=HierarchyRuleExecutionTest -DfailIfNoTests=false -Dcheckstyle.skip
Output location: oap-server/analyzer/dsl-scripts-test/src/test/resources/scripts/hierarchy-rule/*.generated-classes/
all or no argument — generate all DSLs
Run all four commands above sequentially.
After generation
Print the output location for the requested DSL so the user knows where to find the generated .class files. Use javap to decompile:
javap -c -p <path-to-class-file>
Cleaning generated classes
./mvnw clean -pl oap-server/analyzer/dsl-scripts-test
04 同仓库更多 Skills
test
Run unit tests, integration tests, or slow integration tests matching CI. Use to validate changes before submitting a PR.
run-e2e
Run SkyWalking E2E tests locally
package
Rebuild the SkyWalking distribution and OAP Docker image after source changes. Use before running e2e tests so the image reflects your code changes. Avoids the "image looks updated but runtime has stale jars" trap.
new-monitoring-feature
Add a new monitoring target / layer to SkyWalking OAP. Orients you to the OAL / MAL / LAL / TAL / SpanListener extension points, the UI template + submodule touchpoints, the docs set that must move together, and the cross-cutting traps that don't live in any one skill.
license
Check and fix Apache 2.0 license headers and dependency licenses using skywalking-eyes. Use before submitting a PR.
gh-pull-request
Verify, commit, and push changes on a PR branch. Runs pre-flight checks (compile, checkstyle, license headers) before every push. Also creates the PR if one doesn't exist yet.
