Comparison with Baseline
For multicolumn search separate subqueries with semicolon: "IntListBenchmark;manual;1000"
Difference is current score minus baseline score. Positive values are regressions, negative are gains.

2者是一样的，因此如果安装了idea的话，kotlin的环境默认就是可用的
if "%_KOTLIN_COMPILER%"=="" set _KOTLIN_COMPILER=org.jetbrains.kotlin.cli.jvm.K2JVMCompiler
if not "%JAVA_HOME%"=="" (
if exist "%JAVA_HOME%injava.exe" set "_JAVACMD=%JAVA_HOME%injava.exe"
)
if "%_JAVACMD%"=="" set _JAVACMD=java
rem We use the value of the JAVA_OPTS environment variable if defined
set _JAVA_OPTS=-Xmx256M -Xms32M
if not "%_KOTLIN_RUNNER%"=="" (
"%_JAVACMD%" %_JAVA_OPTS% "-Dkotlin.home=%_KOTLIN_HOME%" -cp "%_KOTLIN_HOME%libkotlin-runner.jar" ^
org.jetbrains.kotlin.runner.Main %*
) else (
"%_JAVACMD%" %_JAVA_OPTS% -noverify -cp "%_KOTLIN_HOME%libkotlin-preloader.jar" ^
org.jetbrains.kotlin.preloading.Preloader -cp "%_KOTLIN_HOME%libkotlin-compiler.jar" ^
%_KOTLIN_COMPILER% %*
)
直接从命令行运行kotlin，最终的结果是转换成JAVA字节码的
kotlinc HelloWorld.kt -include-runtime -d HelloWorld.jar
$ java -jar HelloWorld.jar
kotlinc HelloWorld.kt -d HelloWorld.jar
java -cp $KOTLIN_HOME/lib/kotlin-runtime.jar:HelloWorld.jar HelloWorldKt
脚本方式执行
$ kotlinc-jvm -cp joda-time-2.9.4/joda-time-2.9.4.jar
Welcome to Kotlin version 1.1-M04 (JRE 1.8.0_66-internal-b17)
Type :help for help, :quit for quit
>>> import org.joda.time.DateTime
>>> DateTime.now()
