# jdt2jar
2+
3+
`jdt2jar` compiles a JTD schema into a standalone validator JAR at build time.
4+
5+
## CLI
6+
7+
```bash
8+
jdt2jar <schema.json> [options]
9+
```
10+
11+
Options:
12+
13+
- `--output <path>`: output JAR path
14+
- `--package <name>`: generated package name
15+
- `--class <name>`: validator class name
16+
- `--main`: include a standalone `java -jar` entry point
17+
- `--runtime <version>`: target bytecode version
18+
- `--include-sources`: write a companion `.java` file next to the JAR
19+
- `--help`: show usage
20+
21+
## Container
22+
23+
Build with the root `Dockerfile` and run it as a non-root distroless image.
24+
25+
```bash
26+
docker build -t jdt2jar .
27+
docker run --rm jdt2jar --help
28+
syft packages image:jdt2jar
29+
grype jdt2jar
30+
```
