最简单的可能是Kotlin hello world for gradle script Kotlin：
thufir@dur:~/github/gradleScriptKotlin$
thufir@dur:~/github/gradleScriptKotlin$ gradle clean shadowJar;java -jar build/libs/gradleScriptKotlin.jar
> Task :compileKotlin
Using Kotlin incremental compilation
> Task :shadowJar
A problem was found with the configuration of task ':shadowJar'. Registering invalid inputs and outputs via TaskInputs and TaskOutputs methods has been deprecated and is scheduled to be removed in Gradle 5.0.
- No value has been specified for property 'mainClassName'.
The SimpleWorkResult type has been deprecated and is scheduled to be removed in Gradle 5.0. Please use WorkResults.didWork() instead.

Hello gradle script Kotlin world!
thufir@dur:~/github/gradleScriptKotlin$
为简洁起见，请参阅project itself，其中只包含构建文件和kotlin脚本。
如何使用gradle脚本Kotlin构建文件构建可运行的ShadowJar？
答案 0 :(得分：10)
你的意思是胖子吗？ 如果是这样，你可以使用shadow gradle插件：
ObservableCollection<Memo> GetMemo(string searchText = null)
{
if (string.IsNullOrWhiteSpace(searchText))
return _memos;
return _memos.Where(c => c.Title.StartsWith(searchText)) as ObservableCollection<Memo>;
}
如果你想让jar可执行，你还需要将id 'com.github.johnrengelman.shadow' version '2.0.2'
添加到清单（以下是文件Main-class中包含Applicaion.kt的主方法的示例）：
test使用此功能，您可以使用命令jar {
manifest {
attributes 'Main-Class': 'test.ApplicationKt'
}
}
jar
下面我列出了简单的例子。档案java -jar <your jar>：
build.gradle档案plugins {
id 'com.github.johnrengelman.shadow' version '2.0.2'
id "org.jetbrains.kotlin.jvm" version "1.2.21"
}
repositories {
jcenter()
}
jar {
manifest {
attributes 'Main-Class': 'test.ApplicationKt'
}
}
dependencies {
compile("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
compile("org.simpleframework:simple-xml:2.5")
}
：
test.Application.kt运行命令：package test
import org.simpleframework.xml.Element
import org.simpleframework.xml.ElementList
import org.simpleframework.xml.Root
import org.simpleframework.xml.core.Persister
private val testXml = """
<feed>
<entry>
<id> someid </id>
<published> somedate </published>
</entry>
<entry>
<id> someid2 </id>
<published> somedate2 </published>
</entry>
</feed>
""".trimIndent()
@Root(name = "feed", strict = false)
data class Feed(
@field:ElementList(name = "entry", inline = true)
var entriesList: List<Entry>? = null
)
@Root(name = "entry", strict = true)
data class Entry(
@field:Element(name = "id")
var id: String? = null,
@field:Element(name = "published")
var published: String? = null
)
fun main(args: Array<String>) {
println(testXml)
val serializer = Persister()
val example = serializer.read(Feed::class.java, testXml)
println(example)
}
尝试运行jar后：gradle shadowJar
