E.g. in application.properties (for launcher)
foo: Application
loader.main: my.${foo}
loader.path: etc
Spring Boot - Tools
Spring Boot Tools provides a logical grouping for our various build system plugins, and the modules that support them. We provide a spring-boot-maven-plugin and spring-boot-gradle-plugin for Maven and Gradle respectively.
If you are interested in how we support executable archives, take a look at the spring-boot-loader module. If you need to create executable archives from a different build system, spring-boot-loader-tools may help.
