在用第三方的jar時，之前很笨在.m2的repository目錄下手動建置groupId子目錄，其實有現成的語法可以把local的jar檔更新至repository。語法如下：
| mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging> |
這樣在mvn package或mvn install時就不會找不到3rd的jar而無法打包。接著如何設定Jar的MANIFEST.MF，指定Main Class以及把reference的jar全部copy出來。可參考如下pom.xml設定：
| <project>
...
<build>
<finalName>Foo</finalName>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.2</version>
<configuration>
<archive>
<manifest>
<mainClass>com.foo.bar.MainClass</mainClass> <!-- 指定MANIFEST.MF的Main Class -->
<classpathPrefix>lib/</classpathPrefix> <!-- 指定MANIFEST.MF的Class Path的前置 -->
<addClasspath>true</addClasspath> <!-- 指定MANIFEST.MF的Class Path -->
</manifest>
<manifestEntries>
<mode>development</mode>
<url>${pom.url}</url>
</manifestEntries>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration> <!-- Copy相依Jar檔至/target目錄下的lib目錄，也與上述的classpathPrefix標籤相符 -->
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
</project> |
