spring-boot-layertools

Extract Spring Boot layered JARs up to ✨10x faster✨ than the built-in Java CLI.

Usage

This tool uses mmap to load the layered JAR in memory. This is to improve the performance of random-access reads when extracting the layers. As such, this tool is only compatible with Linux.

You can install this tool using cargo install spring-boot-layertools.

```shell $ ./spring-boot-layertools layered.jar extract --destination ./extracted

Java equivalent: java -Djarmode=layertools -jar layered.jar extract --destination ./extracted

$ find ./extracted ./extracted ./extracted/spring-boot-loader ./extracted/spring-boot-loader/org ...

./extracted/dependencies ./extracted/dependencies/BOOT-INF ./extracted/dependencies/BOOT-INF/lib ... ```
