Dependencies¶
VelocityTools requires certain external jar dependencies at different times. These charts should help you determine which jars you need and when.
Since VelocityTools relies on Velocity Engine, please also check Engine dependencies.
Note: VelocityTools 4.x targets the Jakarta EE namespace and requires JDK 11+ for compilation and use. Without skipping tests, building the project from source requires JDK 17, because the showcase example's integration test runs on an embedded Jetty 12 (Jakarta EE 10).
GenericTools¶
| Jar Name | Version | Compile | Tests | Runtime | Notes |
|---|---|---|---|---|---|

| commons-beanutils | 1.9.4 | Yes | Yes | Yes | Required for core infrastructure and several tools |

SLF4J Binding¶
At runtime, Velocity Tools will require an SLF4J binding to be present in the path. Typically, one of:
- AVSL - “A Very Simple Logger”
- SLF4J JDK14 Adapter - redirect logs towards Java 1.4+ logging framework
- SLF4J Log4J Adapter - redirects logs towards Log4J
- SLF4J Simple Logger - minimalistic logger
- SLF4J Android - logger for Android platforms
- LogBack - full featured logging framework
- WebApp SLF4J Logger - redirects logs towards the J2EE container log
