# 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
```bash
./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
```bash
./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
```bash
./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
```bash
./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:
```bash
javap -c -p <path-to-class-file>
```
## Cleaning generated classes
```bash
./mvnw clean -pl oap-server/analyzer/dsl-scripts-test
```
