問題一：

經常遇到公司私服或者中央倉庫沒有的jar包，然后通過各種渠道找到了解決問題的jar包，但是發現沒有pom文件，maven項目引入之后，還有maven在本地倉庫找不到對應jar包的pom文件，打包的時候會在私服下載對應jar包的pom文件而拋出異常，通過maven就可以解決這個問題。前提是你安裝了maven，然后在命令行執行命令就OK了！！！

[ERROR] Failed to execute goal on project AccountEJob: Could not resolve dependencies for project AccountEJob:AccountEJob:jar:1.1.1: Failed to collect dependencies at org.apache.hive:hive-jdbc:jar:1.2.1000.2.6.1.0-129: Failed to read artifact descriptor for org.apache.hive:hive-jdbc:jar:1.2.1000.2.6.1.0-129: Could not transfer artifact org.apache.hive:hive-jdbc:pom:1.2.1000.2.6.1.0-129 from/to nexus (http://XXX.XXX.XXX.XXX:8081/nexus/content/groups/public): Connect to XXX.XXX.XXX.XXX:8081/ [/XXX.XXX.XXX.XXX:8081/] failed: Connection timed out: connect -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

命令：

mvn install:install-file -DgroupId=novaplanet.net -DartifactId=commons-lang -Dversion=2.5 -Dfile=F:/commons-lang-2.5.jar -Dpackaging=jar -DgeneratePom=true
DgroupId：是項目組織唯一的標識符，自己隨便起名
DartifactId：項目的唯一的標識符，自己可以隨便起
Dversion：項目版本
Dfile：jar包路徑（絕對路徑）
DgeneratePom：是否生成pom文件，ture:生成，false：不生成

執行成功，會在本地的maven?jar包目錄下以下結果

問題二：

自己本地的jar包，公司私服上沒有，引入本地的jar包，現在項目的resource目錄下新建lib文件夾，然后將你本地的jar包copy到里面

在maven的配置如下：

<dependencies><dependency><groupId>novaplanet.net</groupId><artifactId>javapns-jdk16-163</artifactId><version>1.2</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/lib/javapns-jdk16-163-1.2.jar</systemPath></dependency></dependencies>

build插入下面配置：

<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><includeSystemScope>true</includeSystemScope></configuration></plugin></plugins></build>

我的實例配置：

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.teset</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>demo</name><description>Demo project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.3.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>novaplanet.net</groupId><artifactId>bcprov-jdk16-145</artifactId><version>1.2</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/lib/bcprov-jdk16-145-1.2.jar</systemPath></dependency><dependency><groupId>novaplanet.net</groupId><artifactId>commons-lang</artifactId><version>2.5</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/lib/commons-lang-2.5.jar</systemPath></dependency><dependency><groupId>novaplanet.net</groupId><artifactId>javapns-jdk16-163</artifactId><version>1.2</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/lib/javapns-jdk16-163-1.2.jar</systemPath></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><includeSystemScope>true</includeSystemScope></configuration></plugin></plugins></build> </project>

引入之后，編譯項目，編譯成功不一定引入成功了，接著打包，看jar包中的classes下的lib中有沒有你需要引入的jar包
