Velocity Dependencies¶
Since 2.1, Velocity Engine requires Java 1.8+.
When building from sources, Maven should fetch all needed dependencies. At runtime, velocity only needs commons-lang, slf4j-api, and one of the slf4j bindings.
The following table lists all needed jars.
| Jar name | Version | Compilation | Tests | Runtime | Comment |
|---|---|---|---|---|---|
| slf4j-api | 1.7.26 | Yes | Yes | Yes | you'll also need an slf4j binding at runtime |
| commons-lang | 3.8.1 | Yes | Yes | Yes | |
| junit | 4.12 | No | Yes | No | |
| hsqldb | 2.3.4 | No | Yes | No | |
| commons-io | 2.6 | No | Yes | No | |
| slf4j-simple | 1.7.26 | No | Yes | No | Your application will need one SLF4J binding, see below |
Here is a list of slf4j bindings:
