本文主要是介绍kotlin build.gradle.kts配置,支持占位符替换文件中变量，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

}// 安装 gradle-6.7
// 编译打包命令: gradle build -Penv=prod -Dfile.encoding=UTF-8 --daemon

kotlin_app/env/config.groovy:

prefix='/output'environments {//192.168.3.165dev {sh{WORK_HOME='/home/boy/kotlin_app';PNAME='kotlin_app';LANG='zh_CN.utf8';JAVA_HOME='/home/boy/jdk/jdk8';}}prod{sh{WORK_HOME='/root/kotlin_app';PNAME='kotlin_app';LANG='zh_CN.utf8';JAVA_HOME='/soft/jre1.8.0_131';}}
}

src/main/resources/logback.xml:  其中包含占位符 @sh.WORK_HOME@

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds"><property name="LOG_HOME" value="@sh.WORK_HOME@/log" /><property name="LOG_NAME" value="${LOG_HOME}/main.log%d{yyyyMMdd}" /><property name="PATTERN" value="%date %p %logger{2} %L - %m%n" /><appender name="C" class="ch.qos.logback.core.ConsoleAppender"><encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"><charset>UTF-8</charset></encoder><encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"><pattern>${PATTERN}</pattern></encoder></appender><appender name="F1" class="ch.qos.logback.core.rolling.RollingFileAppender"><encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"><charset>UTF-8</charset></encoder><rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><FileNamePattern>${LOG_NAME}</FileNamePattern><MaxHistory>30</MaxHistory></rollingPolicy><encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"><pattern>${PATTERN}</pattern></encoder></appender><logger name="org.springframework" level="error" additivity="true" /><logger name="org.eclipse.jetty" level="error" additivity="true" /><!-- <logger name="oracle.jdbc.driver" level="error" additivity="true" /> --><logger name="com.zaxxer.hikari" level="error" additivity="true" /><logger name="com.soft.mapper" level="debug" /><root level="info"><appender-ref ref="C" /></root>
</configuration>

settings.gradle.kts:

     rootProject.name = "a-restful"

 

使用命令编译打包:

gradle build -Penv=dev -Dfile.encoding=UTF-8 --daemon
gradle build -Penv=prod -Dfile.encoding=UTF-8 --daemon

-Penv的值为config.groovy中的配置

执行编译打包命令后,会将config.groovy中配置的变量替换文件中的占位符@xx@

kotlin_app\build\libs下生成jar包名: a-restful-0.0.1.jar
