maven 打包可執行jar的方法

在這以前，我本身找了點maven的東西添加進來

Maven內置變量說明：
	${basedir} 項目根目錄
	${project.build.directory} 構建目錄，缺省爲target
	${project.build.outputDirectory} 構建過程輸出目錄，缺省爲target/classes
	${project.build.finalName} 產出物名稱，缺省爲${project.artifactId}-${project.version}
	${project.packaging} 打包類型，缺省爲jar
	${project.xxx} 當前pom文件的任意節點的內容

方式1

修改pom.xml增長以下內容

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-jar-plugin</artifactId>
	<version>2.4</version>
	<configuration>
		<archive>
			<manifest>
				<addClasspath>true</addClasspath>
				<classpathPrefix>lib/</classpathPrefix>
				<mainClass>com.sysware.HelloWorld</mainClass>
			</manifest>
		</archive>
	</configuration>
</plugin>

運行mvn clean package便可

批註：

通過我本人自測以後發現，這種方式雖然能夠打包，可是不會將依賴包也添加進去。因此我認爲這種方式的打包適合寫一個工具，而後打成JAR包，導入其餘工程使用，若是是一個單獨運行的JAR包，則不適用。

方式2

在pom.xml增長以下內容

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-assembly-plugin</artifactId>
	<version>2.3</version>
	<configuration>
		<appendAssemblyId>false</appendAssemblyId>
		<descriptorRefs>
			<descriptorRef>jar-with-dependencies</descriptorRef>
		</descriptorRefs>
		<archive>
			<manifest>
				<mainClass>com.juvenxu.mvnbook.helloworld.HelloWorld</mainClass>
			</manifest>
		</archive>
	</configuration>
	<executions>
		<execution>
			<id>make-assembly</id>
			<phase>package</phase>
			<goals>
				<goal>assembly</goal>
			</goals>
		</execution>
	</executions>
</plugin>

運行mvn assembly:assembly （ 我本身使用mvn clean package也是能夠的）

批註：

這個方式和方式1不一樣，這種打包方式，將項目及所依賴的全部jar包打包成一個jar，讓打出來的JAR包成爲一個可獨立運行的JAR包

方式3

批註：

    我本身在博主的基礎上，添加了一些配置和註釋

    方式3和方式4都是比較複雜的打包方式，可是能夠本身定義細節，好比須要哪些文件被打包，哪些文件不打包進去，哪些文件放到哪裏等等。
