maven profile

maven profile

1、执行：mvn -P[profile_id]
2、激活activation

< project >
  
   < profiles >
     < profile >
       < id > dev </ id >
       < activation >
         < activeByDefault > false </ activeByDefault >
         < jdk > 1.5 </ jdk >
         < os >
           < name > Windows XP </ name >
           < family > Windows </ family >
           < arch > x86 </ arch >
           < version > 5.1.2600 </ version >
         </ os >
         < property >
           < name > mavenVersion </ name >
           < value > 2.0.5 </ value >
         </ property >
         < file >
           < exists > file2.properties </ exists >
           < missing > file1.properties </ missing >
         </ file >
       </ activation >
      
     </ profile >
   </ profiles >
</ project >

3.当使用属性激活的时候

< profiles >
         < profile >
             < id > test </ id >
             < activation >
                 < property >
                     < name > test.bingo </ name >
                     < value > kkk </ value >
                 </ property >
             </ activation >
</ profile >
</ profiles >

可以在命令行中mvn -Dtest.bingo=kkk或者mvn -Ptest这两种方式激活该profile对pom设置的进行覆盖。

4.当使用变量替换的时候

< 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/maven-v4_0_0.xsd" >
    
     < build >
         < resources >
             < resource >
               < directory > src/main/filter-resources </ directory >
               < filtering > true </ filtering >
             </ resource >
         </ resources >

     </ build >
     < profiles >
         < profile >
             < id > test </ id >
             < activation >
                 < property >
                     < name > test.bingo </ name >
                     < value > kkk </ value >
                 </ property >
             </ activation >
             < properties >
                 < env .dir > 222 </ env.dir >
             </ properties >
             < build >
                         </ profile >
     </ profiles >
</ project >

过滤指定的目录下文件，如果该文件中有${env.dir}的变量，就会被222给覆盖掉。
