maven学习笔记(定制普通Java一个项目)

创建一个新项目:

mvn archetype:generate -DgroupId=cn.net.comsys.ut4.simpleweather -DartifactId=simple-weather -DpackageName=cn.net.comsys.ut4.simpleweather -Dversion=1.0

generate目标文档:Generate project in batch mode

为pom.xml添加一些项目信息如下:

<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>cn.net.comsys.ut4.simpleweather</groupId>
  <artifactId>simple-weather</artifactId>
  <version>1.0</version>
  <packaging>jar</packaging>

  <name>simple-weather</name>

</licenses>

<organization>
	<name>COMSYS</name>
	<url>http://WWW.COMSYS.NET.CN</url>
</organization>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

Maven Exec 插件

install成jar后可以通过exec执行main方法

mvn exec:java -Dexec.mainClass=org.sonatype.mavenbook.weather.Main

Exec 插件让我们能够在不往 classpath 载入适当的依赖的情况下,运行这个程序

查看exec插件目标以及参数帮助:

mvn help:describe -Dplugin=exec -Dfull

查看项目依赖:

 mvn dependency:resolve
mvn dependency:tree

执行单元测试:

 mvn test

  忽略测试失败:<testFailureIgnore>true</testFailureIgnore>

<project>
	[...]
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-plugin</artifactId>
				<configuration>
					<testFailureIgnore>true</testFailureIgnore>
				</configuration>
			</plugin>
		</plugins>
	</build>
	[...]
</project>

  也可以通过命令行参数设置

 mvn test -Dmaven.test.failure.ignore=true

  

跳过单元测试:

mvn install -Dmaven.test.skip=true

  

构建一个打包好的命令行应用程序

想pom.xml增加一下内容

<project>
	[...]
	<build>
		<plugins>
			<plugin>
				<artifactId>maven-assembly-plugin</artifactId>
				<configuration>
					<descriptorRefs>
						<descriptorRef>jar-with-dependencies</descriptorRef>
					</descriptorRefs>
				</configuration>
			</plugin>
		</plugins>
	</build>
	[...]
</project>

  运行以下命令进行装配:

mvn install assembly:assembly
