maven打包慢，使用maven-mvnd 打包可以快一半

maven打包打包系统包时，因子工程模块很多，打包越来越慢。。

今天试试mavend，比maven打包更快的包。

打包后，发现时间比原来的，缩短了

打开 https://github.com/apache/maven-mvnd/releases 找到想要的包linux版

下载

# mkdir -p /app/mvnd

# cd /app/mvnd

# wget https://github.com/apache/maven-mvnd/releases/download/1.0-m6/maven-mvnd-1.0-m6-m39-linux-amd64.zip

解压

# cd /app/mvnd
# unzip maven-mvnd-1.0-m6-m39-linux-amd64.zip
# vi maven-mvnd-1.0-m6-m39-linux-amd64/conf/mvnd.properties
找到 maven.settings，放开注解，将settings.xml配置上
maven.settings=/app/system/settings.xml

环境变量配置etc

增加mavend的配置增加到配置中

# vi /etc/profile
在文件末尾增加如下配置
# vi harbor.yml
export MAVEN_HOME_D=/app/mvnd/maven-mvnd-1.0-m6-m39-linux-amd64
export PATH=${MAVEN_HOME_D}/bin:${PATH}

测试

mvn打包命令修改

之前打包命令，直接修改mvn 为mvnd
mvn clean install -DskipTests=true -s $CURRENT_PATH/settings.xml
修改为
mvnd clean install -DskipTests=true -s $CURRENT_PATH/settings.xml

发现编辑打包的速度，快乐1/2左右。

打包命令修改

#!/bin/bash
CODE_PATH="code"
PROJECT_NAME="mygod-biz"
GIT_ADDR="$GIT_URL/$PROJECT_NAME.git"
JAVA_HOME=$JAVA_17HOME

OLD_PATH=`pwd`
LINK_PATH=`readlink $0`
[ "x" = "x$LINK_PATH" ] && CURRENT_PATH=`dirname $0`
[ "x" != "x$LINK_PATH" ] && CURRENT_PATH=`dirname $LINK_PATH`
cd $CURRENT_PATH
CURRENT_PATH=`pwd`

#判断文件夹是否存在 -d
if [[ ! -d $CURRENT_PATH/$CODE_PATH/$PROJECT_NAME ]]; then
 mkdir -p $CURRENT_PATH/$CODE_PATH
 cd $CURRENT_PATH/$CODE_PATH
 git clone $GIT_ADDR
 cd $CURRENT_PATH/$CODE_PATH/$PROJECT_NAME
 git checkout $PROJECT_BRANCH
fi
cd $CURRENT_PATH/$CODE_PATH/$PROJECT_NAME
git checkout $PROJECT_BRANCH
git pull
mvnd clean install -DskipTests=true -s $CURRENT_PATH/settings.xml

执行命令

 命令修改前后打包时间对比

修改前

mvn clean install -DskipTests=true -s $CURRENT_PATH/settings.xml

修改后

mvnd clean install -DskipTests=true -s $CURRENT_PATH/settings.xml

结论：确实快了不少。
