# Java Backend Context

## Imports
```java
import com.dotmarketing.util.Config;
import com.dotmarketing.util.Logger;
import com.dotmarketing.util.UtilMethods;
import com.dotcms.util.CollectionsUtils;
```

## Patterns
- Config: `Config.getStringProperty("key", "default")` – never System.getProperty.
- Logging: `Logger.info(this, "msg")` – never System.out.
- Null: `UtilMethods.isSet(s)` before use.
- APIs: `APILocator.getUserAPI()`, etc.
- Exceptions: DotDataException, DotSecurityException.
- Data classes: `@Value.Immutable` + builder.

## Maven (CRITICAL)
- Versions only in `bom/application/pom.xml`. Dependencies in `dotCMS/pom.xml` without versions.

## Java
- Core: Java 11 syntax. CLI: Java 21 ok. Runtime: Java 21.

## Build
```bash
./mvnw install -pl :dotcms-core -DskipTests
./mvnw -pl :dotcms-core -Pdocker-start -Dtomcat.port=8080
./mvnw -pl :dotcms-integration verify -Dcoreit.test.skip=false
```
