Beangle Boot toolkit
It provides a smart mechanism to bootstrap jar.Unlike other boot libraries which building flatjar, beangle-boot just detects dependencies list in jarfile!/META-INF/beangle/dependencies.
The dependencies file contains many lines,each line discribe a artifact gav(group:artifact:version) info, that corresponding jar can be fetched by maven repo.
Put this config fragment in your project plugin.sbt file.
addSbtPlugin("org.beangle.build" % "sbt-beangle-build" % "0.0.14")
A executable jar should contain Main-Class in /META-INF/MANIFEST.MF.The configuration can be appended by jar plugin.
Compile / packageBin / packageOptions +=
Package.ManifestAttributes(java.util.jar.Attributes.Name.MAIN_CLASS -> "org.your.main.class.name")
Compile / compile := (Compile / compile).dependsOn(BootPlugin.generateDependenciesTask).value
After that,use sbt package will generate a package which contains the dependencies file.
wget https://github.com/beangle/boot/tree/main/src/main/scripts/launch.sh
chmod +x launch.sh
./launch.sh /path/to/your/project.jar
To append additional library to object jar's classpath,using format:
./launch.sh -cp "/path/to/lib/*" /path/to/your/project.jar
Specify properties using -Dxx=vv
./launch.sh -cp "/path/to/lib/*" -Dk1=v1 -Dk2=v2 /path/to/your/project.jar arg1 arg2
The difference with java command is that -jar option is ommited.
