如何使用gradle脚本Kotlin构建文件构建可运行的ShadowJar? [英] How to build a runnable ShadowJar with a gradle script Kotlin build file?
问题描述
Simplest possible 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$
For the sake of brevity please refer to the project itself which only really consists of the build file and a kotlin script.

推荐答案
您是说fatjar吗? 如果是这样,您可以使用shadow gradle插件:
Do you mean fatjar? If so, you could use shadow gradle plugin:
id 'com.github.johnrengelman.shadow' version '2.0.2'
如果要使jar可执行,还需要添加Main-class
来进行清单化(下面的文件Applicaion.kt
中的主方法示例,包为test
):
And if you want to make jar executable, you need also add Main-class
to manifest (below example for main method in file Applicaion.kt
with package test
):
jar {
manifest {
attributes 'Main-Class': 'test.ApplicationKt'
}
}
与此同时,您可以使用以下命令运行jar
:java -jar <your jar>
And with this you may run jar
with command: java -jar <your jar>
下面我有一个简单的例子.文件build.gradle
:
Below I have include simple example. File build.gradle
:
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")
}
文件test.Application.kt
:
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)
}
运行命令:gradle shadowJar
然后尝试运行jar:java -jar build/libs/shadow_test-all.jar
And after try to run jar: java -jar build/libs/shadow_test-all.jar
