Maven如何打包并生成运行脚本

2024-12-12 技术教程

这篇文章主要为大家展示了Maven如何打包并生成运行脚本，内容简而易懂，希望大家可以学习一下，学习完之后肯定会有收获的，下面让小编带大家一起来看看吧。

1.定义插件

<properties><maven-jar-plugin.version>2.4</maven-jar-plugin.version><maven-assembly-plugin.version>2.4</maven-assembly-plugin.version><maven-compiler-plugin.version>3.7.0</maven-compiler-plugin.version></properties><plugins> <plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>${maven-compiler-plugin.version}</version><configuration><source>${java.version}</source><target>${java.version}</target><encoding>${project.build.sourceEncoding}</encoding></configuration><executions><execution><phase>compile</phase><goals><goal>compile</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId><version>${maven-jar-plugin.version}</version><configuration><archive><addMavenDescriptor>true</addMavenDescriptor><manifest><addClasspath>true</addClasspath></manifest></archive><excludes></excludes></configuration></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-assembly-plugin</artifactId><version>${maven-assembly-plugin.version}</version><configuration><descriptors><descriptor>${project.basedir}/../assembly/assembly.xml</descriptor></descriptors></configuration><executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>single</goal></goals></execution></executions></plugin></plugins>

2.assembly配置

<assembly><id>bin</id><formats><format>tar.gz</format></formats><dependencySets><dependencySet><useProjectArtifact>false</useProjectArtifact><outputDirectory>lib</outputDirectory><unpack>false</unpack><scope>runtime</scope></dependencySet><dependencySet><useProjectArtifact>false</useProjectArtifact><outputDirectory>lib</outputDirectory><unpack>false</unpack><scope>system</scope></dependencySet></dependencySets><fileSets><fileSet><directory>${project.basedir}/../scripts</directory><outputDirectory>bin</outputDirectory><fileMode>0644</fileMode><directoryMode>0755</directoryMode><filtered>true</filtered></fileSet><fileSet><directory>${project.basedir}/src/main/resources</directory><outputDirectory>config</outputDirectory><fileMode>0644</fileMode><directoryMode>0755</directoryMode><includes><include>*.xml</include><include>*.json</include><include>*.properties</include></includes><filtered>true</filtered></fileSet><fileSet><directory>${project.build.directory}</directory><outputDirectory>lib</outputDirectory><includes><include>*.jar</include></includes></fileSet><fileSet><directory>${project.basedir}</directory><outputDirectory>doc</outputDirectory><includes><include>README*</include><include>LICENSE*</include><include>NOTICE*</include></includes></fileSet></fileSets></assembly>

3.脚本

#!/bin/sh#server id -- changeSERVER_ID=#java homeJAVA_HOME=#java commandJAVA_CMD=`which java`#jvm optionJVM_OPT="-Xmx1024M -Xms512M -server -XX:+PrintGCDetails -XX:+PrintGCDateStamps"#jar nameJAR=${project.artifactId}-${project.version}.jar#main classMAIN_CLASS=${MainClass}# main class argsARGS="${StartArgs}"#environmentENVIRONMENT=${profiles.environment}#cd working pathcd_working_path(){ cd `dirname $0` cd ..}#jarjar(){ WK_PATH=`pwd` /usr/bin/nohup ${JAVA_CMD} -Denvironment=${ENVIRONMENT} -Dlog4j.configurationFile=${WK_PATH}/config/log4j2.xml ${JVM_OPT} -cp ${WK_PATH}/lib/${JAR}:${WK_PATH}/lib/* ${MAIN_CLASS} ${ARGS} >/dev/null 2>&1 &}#get pidget_pid(){ echo `ps -ef | grep ${JAR} | grep server_id=${SERVER_ID} |grep -v 'grep' |awk '{print $2}'`}#checkcheck(){ #check server id if [ ! -n "$SERVER_ID" ];then echo "Please set up the server id 'SERVER_ID'" exit fi}#start servicestart(){ #check check #check pid PID=`get_pid` if [ -n "$PID" ];then echo "Process exists, PID >> "${PID} exit fi #check java if [ -n "$JAVA_HOME" ];then JAVA_CMD=${JAVA_HOME}/bin/java fi #start service ${JAVA_CMD} -version jar #check if [ $? -ne 0 ];then echo "Service startup failed." exit fi #check service PID=`get_pid` if [ ! -n "$PID" ];then echo "Service startup failed." else echo "Service startup success, Current environment is ${ENVIRONMENT} , PID >> "${PID} fi}#stop servicestop(){ #check check #check pid PID=`get_pid` if [ ! -n "$PID" ];then echo "Process not exists." else kill ${PID} echo "Kill pid >> '$PID'" if [ $? -ne 0 ];then echo "Service shutdown failed." exit else echo "Service shutdown success." fi fi}#restart servicerestart(){ #stop service stop COUNT=0 while true do PID=`get_pid` if [ ! -n "$PID" ];then #start service start break else let COUNT++ echo "Restarting..." if [ ${COUNT} -eq 3 ];then echo "Restart error" exit fi fi sleep 3 done}#check statestate(){ PID=`get_pid` if [ ! -n "$PID" ];then echo "Service not exists." else echo "Service status is normal, PID >> '$PID'" fi}#mainmain(){ #cd working path cd_working_path if [ ! -n "$1" ];then echo "***********************************************" echo "* start : Start service *" echo "* stop : Stop service *" echo "* restart : Restart service *" echo "* state : Check service state *" echo "***********************************************" read -p "Please choose >> ": CASE PARAMETER=${CASE} else PARAMETER=$1 fi case "$PARAMETER" in start) start ;; stop) stop ;; restart) restart ;; state) state ;; *) main ;; esac}main $1

PS：下面看下Maven打包生成可运行bat/sh脚本文件

利用Maven的appassembler-maven-plugin插件，就可以实现自动打包可运行的脚本，还可以跨平台。

<plugin> 　　<groupId>org.codehaus.mojo</groupId> 　　<artifactId>appassembler-maven-plugin</artifactId> <version>1.1.1</version> <configuration> 　　<repositoryLayout>flat</repositoryLayout> 　　<repositoryName>lib</repositoryName> 　　<configurationSourceDirectory>src/main/resources/conf</configurationSourceDirectory> 　　 <configurationDirectory>conf</configurationDirectory>  <copyConfigurationDirectory>true</copyConfigurationDirectory>  <includeConfigurationDirectoryInClasspath>true</includeConfigurationDirectoryInClasspath>  <binPrefix>startup</binPrefix>  <assembleDirectory>${project.build.directory}/server</assembleDirectory>  <extraJvmArguments>-Xms768m -Xmx768m -XX:PermSize=128m 　　-XX:MaxPermSize=256m -XX:NewSize=192m -XX:MaxNewSize=384m </extraJvmArguments>  <platforms> 　　<platform>windows</platform> 　　 <platform>unix</platform> </platforms> <programs> 　　<program> 　　<mainClass>com.coderli.onecoder.server.HypervisorServer</mainClass> 　　　　<name>startup</name> </program> </programs> 　　</configuration></plugin>

然后选择要编译的工程，右键->maven build… 命令如下图：
