maven 将本地jar包打入jar包中

有关MAVEN仓库的理解参见:http://blog.csdn.net/wanghantong/article/details/36427433

MAVEN依赖关系中Scope的作用

Java代码  maven 将本地jar包打入jar包中
  1. Dependency Scope 在POM 4中,<dependency>中还引入了<scope>,它主要管理依赖的部署。目前依赖项的作用域<scope>可以使用5个值:    
  2. 在定义项目的依赖项的时候,我们可以通过scope来指定该依赖项的作用范围。scope的取值有compile、runtime、test、provided、system和import。  
  3. compile:这是依赖项的默认作用范围,即当没有指定依赖项的scope时默认使用compile。compile范围内的依赖项在所有情况下都是有效的,包括运行、测试和编译时。  
  4. runtime:表示该依赖项只有在运行时才是需要的,在编译的时候不需要。这种类型的依赖项将在运行和test的类路径下可以访问。  
  5. test:表示该依赖项只对测试时有用,包括测试代码的编译和运行,对于正常的项目运行是没有影响的。  
  6. provided:表示该依赖项将由JDK或者运行容器在运行时提供,也就是说由Maven提供的该依赖项我们只有在编译和测试时才会用到,而在运行时将由JDK或者运行容器提供。  
  7. system:当scope为system时,表示该依赖项是我们自己提供的,不需要Maven到仓库里面去找。指定scope为system需要与另一个属性元素systemPath一起使用,它表示该依赖项在当前系统的位置,使用的是绝对路径。  

 

Java代码  maven 将本地jar包打入jar包中
  1. POM文件里面可以引用一些内置属性(Maven预定义可以直接使用)  
  2.   
  3. ${basedir} 项目根目录   
  4. ${version}表示项目版本;  
  5. ${project.basedir}同${basedir};  
  6. ${project.version}表示项目版本,与${version}相同;  
  7. ${project.build.directory} 构建目录,缺省为target  
  8. ${project.build.sourceEncoding}表示主源码的编码格式;  
  9. ${project.build.sourceDirectory}表示主源码路径;  
  10. ${project.build.finalName}表示输出文件名称;  
  11. ${project.build.outputDirectory} 构建过程输出目录,缺省为target/classes  

 

如何在Maven项目中引入本地包呢?

比如我从其它项目打一个jar包,引入到现有项目中。

方法一:将待引入的包放在目录下如lib目录下,修改pom文件,加入依赖并且scope要设置为system

 

Java代码  maven 将本地jar包打入jar包中
  1. <dependencies>  
  2.     <dependency>  
  3.         <groupId>com.fbcds</groupId>  
  4.         <artifactId>fbcds</artifactId>  
  5.         <version>1.0</version>  
  6.         <scope>system</scope>  
  7.         <systemPath>${project.basedir}/lib/fbcds.jar</systemPath>  
  8.     </dependency>  
  9. </dependencies>  

 
maven 将本地jar包打入jar包中


 上面设置完成后,运行mvn package命令执行成功。但打出来的包里面不包含lib目录和fbcds.jar这个引用的包,即打出来的包不是可执行的jar。所以个人开发的话可以使用这种方式,如果团队开发请使用方法二。

 

方法二:将待引入的jar包安装到本地repository中

1、先把待引入的jar包放在一个目录下,需要改一下包名,如fbcds.jar修改成fbcds-1.0.jar,如F:\lib目录,在命令行CD到lib目录,执行以下命令:

Java代码  maven 将本地jar包打入jar包中
  1. mvn install:install-file -Dfile=fbcds-1.0.jar -DgroupId=fbcds -DartifactId=fbcds -Dversion=1.0 -Dpackaging=jar  
  2. mvn install:install-file -Dfile=ojdbc7-1.0.jar -DgroupId=ojdbc7 -DartifactId=ojdbc7 -Dversion=1.0 -Dpackaging=jar  

 2、修改项目pom文件加入包对应的依赖

 

Java代码  maven 将本地jar包打入jar包中
  1. <dependencies>  
  2.     <dependency>  
  3.       <groupId>log4j</groupId>  
  4.       <artifactId>log4j</artifactId>  
  5.       <version>1.2.17</version>  
  6.     </dependency>  
  7.     <dependency>  
  8.       <groupId>fbcds</groupId>  
  9.       <artifactId>fbcds</artifactId>  
  10.       <version>1.0</version>  
  11.     </dependency>  
  12.     <dependency>   
  13.       <groupId>ojdbc7</groupId>  
  14.       <artifactId>ojdbc7</artifactId>  
  15.       <version>1.0</version>   
  16.     </dependency>  
  17.   </dependencies>  

 上面的fbcds和ojdbc7就是新加的引用包的依赖。

 完成后,在本地仓库可看到对应的文件夹内容:

MAVEN如何打可执行的JAR包

前提条件:已成功将待引入的jar包安装到本地repository中

方法一、使用maven-shade-plugin插件打可执行的jar包

插件查找链接:http://maven.apache.org/plugins/

1、测试类代码

 

Java代码  maven 将本地jar包打入jar包中
  1. package com.lwf.test;  
  2.   
  3. import java.sql.Connection;  
  4. import java.sql.DriverManager;  
  5. import java.sql.ResultSet;  
  6. import java.sql.SQLException;  
  7. import java.sql.Statement;  
  8.   
  9. import com.eclink.fbcis.store.StoreDao;  
  10.   
  11. public class TestClass {  
  12.     public static void main(String[] args) {  
  13.         StoreDao a = new StoreDao();  
  14.         System.out.println("------" + a.toString());  
  15.         Connection con = null;  
  16.         Statement st = null;  
  17.         ResultSet rs = null;  
  18.         try {  
  19.             String sql = "select * from temp_head where temp_no='C530015I19008015'";  
  20.             Class.forName("oracle.jdbc.driver.OracleDriver");  
  21.             con = DriverManager.getConnection("jdbc:oracle:thin:@//10.101.2.19:1521/pdbqmytcis","qmytcis","qmytcis123");  
  22.             st = con.createStatement();  
  23.             rs = st.executeQuery(sql);  
  24.             if(rs.next()){  
  25.                 System.out.println(rs.getString("temp_no"));  
  26.             }  
  27.               
  28.         } catch (Exception e) {  
  29.             e.printStackTrace();  
  30.         } finally{  
  31.             try {  
  32.                 rs.close();  
  33.                 st.close();  
  34.                 con.close();  
  35.             } catch (SQLException e) {  
  36.                 e.printStackTrace();  
  37.             }  
  38.         }  
  39.     }  
  40. }  

 上面类中引用到了fbcds和ojdbc7包的内容。

2、对应pom文件

Java代码  maven 将本地jar包打入jar包中
  1. <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">

  45.             </plugin>  
  46.         </plugins>  
  47.     </build>  
  48.   
  49. </project>  

 在eclipse中右键项目run as 选择Maven package,可看打包的target目录内容:

 比较两个包内容:

 执行包:cmd下

 original-MavenPackage-0.0.1-SNAPSHOT.jar中没有主清单属性是执行不了的。

方法二、使用maven-assembly-plugin插件打可执行的jar包

测试类与方法一中一样,只是pom不一样,pom文件如下:

maven 将本地jar包打入jar包中

maven 将本地jar包打入jar包中

可以看到依赖的包拷贝到了lib目录下,打的包里没有依赖包的信息,只是简单的包,不过Manifest文件class-path要包含引用名的路径

 在以上前三种插件打包方式中,maven-shade-plugin和maven-assembly-plugin采取的是将依赖包解压再一并打到新包中,这样依赖包可能存在冲突的时候,导致运行时可能出现未知问题,而onejar-maven-plugin打包是将依赖包自动归入lib目录,不解压原包,相当于在原包基础上加壳,这样可以避免冲突的发生。第四种方法即是我们原来ant打包所使用的方法。
