使用IntelliJ，我可以让我的Kotlin (JVM)项目运行。但是，当我尝试使用java命令运行它时，它失败了。

我是这样从Jenkins运行的:
#!/bin/bash
cd /support/d63/copper/manifest_writer/dev
export SPRING_PROFILES_ACTIVE=dev
./run.sh
这是run.sh:
#!/bin/bash
JAVA_HOME=/usr2/jest/openjdk/java11
#This ensures that UTF-8 is always used, even for encoding file names.
export LC_ALL=en_US.UTF-8
cd /support/d63/copper/manifest_writer/dev
JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF-8"
JAVA_OPTS="$JAVA_OPTS -Djava.security.egd=file:/dev/./urandom"
$JAVA_HOME/bin/java $JAVA_OPTS -jar content-acq-copper-manifest-writer-0.0.1-SNAPSHOT.jar $*
这是我的开始课:
package org.cas.eo.contentacq.contentacqcoppermanifestwriter
import org.cas.eo.contentacq.contentacqcoppermanifestwriter.props.ProcessProps
import org.springframework.boot.ApplicationArguments
import org.springframework.boot.ApplicationRunner
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.context.properties.ConfigurationPropertiesScan
import org.springframework.boot.runApplication
@SpringBootApplication
@ConfigurationPropertiesScan
class Application (
private val controller: Controller,
private val processProps: ProcessProps
): ApplicationRunner {
fun main(args: Array<String>) {
runApplication<Application>(*args)
}
override fun run(args: ApplicationArguments) {
if (processProps.logOnly){
controller.logManifests()
} else {
controller.writeManifests()
}
}
}
我运行mvn clean package来获取我的罐子。

由于它在IntelliJ中工作，但在使用java命令运行时不起作用，我认为我在那里做错了什么。
(只是抓稻草…)
我想到一件事:你的main()方法是一个实例方法，我没有看到，可能是一个问题。
在独立程序中，main()不能是实例方法，因为还没有实例可以调用它。我不知道Spring加载器是否对这种情况有特殊的考虑，但如果没有，我建议尝试将其移动到companion object:
class Application(/* … */): ApplicationRunner {
companion object {
fun main(args: Array<String>) {
runApplication<Application>(*args)
}
}
// …
或输出到顶级函数:
class Application(/* … */): ApplicationRunner {
// …
}
fun main(args: Array<String>) {
runApplication<Application>(*args)
}
在后一种情况下，必须将Kt附加到start-class标记(或指定要运行的类的名称的任何地方)，因为这是Kotlin/JVM编译器处理顶级函数的方式。
这是一个风格的问题，你喜欢哪一个;同伴对象封装得更严密，但顶级函数更简单、更简洁。(因为在任何项目中通常都不会有太多这样的人，所以很少有混淆或冲突的危险。)
