• base on repository (as a rust project) in JweustExtention.JweustRoot dir, in runtime, it'll create a git branch of the subprojects, and commit the changes to the branch, check,fetch and merge the newer tag is released*.
• to configuration the rust, it'll generate the rust files from (tasks or gradle)'s configuration automatically.

plugins {
    alias(libs.plugins.shadowJar)
    alias(libs.plugins.jweust) // or id("me.heizi.jweust")
}
// ...configuration jar before jweust
shadowJar {
    mainClass = "..."
}
jweust {
    defaults()
    JweustRoot = file("...") // default is buildDir/tmp/jweust
    rustProjectName = "..." // default is project.name.snackCased
    version = "..." // default is project.version.`parse to x.x.x`
    jre {
        search += JvmDir(".runtime/") // search jre in exe locate/.runtime/ dir
        search += EnvVar("JDK_17_HOME") // it will search JAVA_HOME by default
        min = "17" // min version
        max = "17" // max version
    }
    jar {
        // jar file to run
        // it will use shadowJar's output or jar's by default
        // if you want to use other jars, you can set it here
        files += project.tasks.named<ShadowJar>("shadowJar").get().archiveFile.get().asFile
        laucnher {
            file = 0 // index of files
            args = mapOf(-1 to "arg",Int::MAX_VALUE to "--Xmx-OrSomething" ) // args to pass to java
            mainClass // ....
        }
    }
    exe {
        // define the information of exe
        // see Microsoft's document for more information `windows executable resource `
        icon = File("...")

        jvm = "...".toCharset() 
    }
