几种常用的maven打包插件总结:
一、自带插件:
maven自带的核心插件为Build plugins和Reporting plugins。
mvn compile编译源码实际上就利用到了maven-compiler-plugin,其他phase也类似用到了相应的插件
关于maven自带的核心插件见:http://maven.apache.org/plugins/index.html
核心插件 maven-compiler-plugin
参考地址 http://maven.apache.org/plugins/maven-compiler-plugin/
从3.0版本开始,编译工具默认使用的是 javax.tools.JavaCompiler(从JDK 1.6开始) 如果要强制使用javac来进行编译,需要添加参数forceJavacCompilerUse
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-compiler-pluginartifactId>
<version>3.6.1version>
<configuration>
<encoding>utf-8encoding>
<source>1.7source>
<target>1.7target>
<compilerArgs>
<arg>-verbosearg>
<arg>-Xlint:all,-options,-patharg>
compilerArgs>
<fork>truefork>
<meminitial>128mmeminitial>
<maxmem>512mmaxmem>
<executable>${JAVA_1_4_HOME}/bin/javacexecutable>
<compilerVersion>1.3compilerVersion>
configuration>
plugin>
配置source 和target时,也可以这样配置 实际上这是javac指令可以接受的参数
.compiler.source>1.8 .compiler.source>
.compiler.target>1.8 .compiler.target>
二、直接打成可执行的jar包。
这种打包方式比较粗暴,将应用的依赖包和程序包打成一个全量包。包会相对较大,但是好处也很明显,不用管依赖包。所以这种方式只适用于比较小的项目,比如搭建微服务这种方式可以适用。
附上关键的服务器执行代码
java -jar dataCleaner.jar 1>/home/credit/app/tracefile 2>/home/credit/app/errorfile &
说明: 最后面的& 表明后台执行。
1> 将运行日志输出到tracefile
2> 将错误日志输出到errorfile
具体参数很多,参考官网页面
官网页面 http://maven.apache.org/plugins/maven-assembly-plugin/assembly.html
<plugin>
<artifactId>maven-assembly-pluginartifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependenciesdescriptorRef>
descriptorRefs>
configuration>
plugin>
还一种方式,可以使用spring-boot的打包插件进行打包。一般是跟spring boot一起使用的,但是也可以单独利用出来打成可执行的整包。
<plugin>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-maven-pluginartifactId>
<version>1.3.5.RELEASEversion>
<configuration>
<mainClass>com.ftoul.dataCleaner.DataCleanServiceProvidermainClass>
<layout>ZIPlayout>
configuration>
<executions>
<execution>
<goals>
<goal>repackagegoal>
goals>
execution>
executions>
plugin>
补充一下,还有一个shade插件也是比较常用的打fat jar包的方式
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-shade-pluginartifactId>
<version>3.0.0version>
<executions>
<execution>
<phase>packagephase>
<goals>
<goal>shadegoal>
goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<manifestEntries>
<Main-Class>org.sonatype.haven.ExodusCliMain-Class>
<Build-Number>123Build-Number>
manifestEntries>
transformer>
transformers>
configuration>
execution>
executions>
plugin>
三 将依赖包与代码包分开打包
这种打包方式更普遍适用。毕竟依赖的jar包在项目发展中变动会相对较小。一般可配合maven-dependency-plugin 和 maven-jar-plugin 两个插件打包。前者负责依赖包,后者负责程序包。
另外,附上服务器可用的执行脚本。
more runapp.sh
#!/bin/sh
#执行jar包
RUN_LIBS=""
#依赖jar包
SUPPORT_LIBS=""
RUN_LIB_PATH="$HOME/app/lib"
SUPPORT_LIB_PATH="$HOME/app/support"
#加载程序包
for i in ${RUN_LIB_PATH}/* ; do
RUN_LIBS=${RUN_LIBS}:$i
done
#加载依赖包
for i in ${SUPPORT_LIB_PATH}/* ; do
SUPPORT_LIBS=${SUPPORT_LIBS}:$i
done
#整合classpath
CLASSPATH=${RUN_LIBS}:${SUPPORT_LIBS}
export CLASSPATH
#调用java指令执行。-D输入参数 java中可以用 System.getProperties读取。同时指定执行入口类 SpringBootApplication 这是一个典型的Springboot的执行方式。
java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,address=27899,suspend=n -cp $CLASSPATH -Dspring.profiles.active=prod com.app.SpringBootApplication -D
user.timezone=GMT+08 1>/home/credit/ftoulcloud/bin/tracefile 2>/home/credit/ftoulcloud/bin/errorfile &
echo Start App Success!
assembly官网的其他几个示例使用项目的依赖包进行打包
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-dependency-pluginartifactId>
<version>3.0.0version>
<executions>
<execution>
<id>src-dependenciesid>
<phase>packagephase>
<goals>
<goal>unpack-dependenciesgoal>
goals>
<configuration>
<classifier>sourcesclassifier>
<failOnMissingClassifierArtifact>falsefailOnMissingClassifierArtifact>
<outputDirectory>${project.build.directory}/sourcesoutputDirectory>
configuration>
execution>
executions>

将指定的包打入依赖包
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-dependency-pluginartifactId>
<version>3.0.0version>
<executions>
<execution>

一个可用的示例
<plugin>

goals>
<configuration>
<outputDirectory>exportoutputDirectory>
<excludeTransitive>falseexcludeTransitive>
<stripVersion>truestripVersion>
configuration>
execution>
executions>
plugin>
四、maven-jar-plugin 将指定的一些文件打包成jar包
这个比较简单。就将指定的文件打成jar包
<plugin>
<groupId>org.apache.maven.pluginsgroupId>
<artifactId>maven-jar-pluginartifactId>
<version>3.0.2version>
<configuration>
<archive>
<manifest>
<addClasspath>trueaddClasspath>
<classpathPrefix>support/classpathPrefix>
<mainClass>com.myapp.MyAppApplicationmainClass>
<manifestFile>${project.build.outputDirectory}/META-INF/MANIFEST.MFmanifestFile>
manifest>
archive>
configuration>
<executions>
<execution>
<id>myapp1-jarid>
<phase>packagephase>
<goals>
<goal>jargoal>
goals>
<configuration>
<classifier>myappclassifier>
<includes>
<include>com/myapp/**include>
<include>mybatis/**include>
<include>templates/**include>
<include>*.propertiesinclude>
<include>dubbo.xmlinclude>
includes>
configuration>
execution>
<execution>
<id>myapp2-jarid>
<phase>packagephase>
<goals>
<goal>jargoal>
goals>
<configuration>
<classifier>myapp2classifier>
<includes>
<include>com/myapp2/crawler/*include>
<include>com/myapp2/crawler/*include>
<include>com/myapp2/utils/**include>
<include>log4j.propertiesinclude>
includes>
configuration>
execution>
executions>
plugin>

没事可以经常去官网转转,时不时有些新的打包插件出来。 比如PDF插件 GPG签名插件 TOMCAT插件 JETTY插件 等。 好多好多。用时慢慢去了解。
