    Maven實在是個很方便的東西，管好了library寫程式的心情大悅 XDD
    目前都是用Eclipse所以也就很自然的用Eclipse的Plugin，又所以更自然的遇到了一些問題!!

• 調整預設的Compiler版本
• 自動把Maven library放進WEB-INF/lib資料夾

調整預設的Compiler版本

    pom.xml <project> 裡面加入設定

<build> <plugins> <plugin> <groupid>org.apache.maven.plugins</groupId> <artifactid>maven-compiler-plugin</artifactId> <version>2.1</version> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> </plugins> </build>

自動把Maven library放進WEB-INF/lib資料夾

先在 project>build 中加入
<pluginmanagement> <plugins> <!-- Ignore/Execute plugin execution --> <plugin> <groupid>org.eclipse.m2e</groupId> <artifactid>lifecycle-mapping</artifactId> <version>1.0.0</version> <configuration> <lifecyclemappingmetadata> <pluginexecutions> <pluginexecution> <pluginexecutionfilter> <groupid>org.apache.maven.plugins</groupId> <artifactid>maven-dependency-plugin</artifactId> <versionrange>[2.0,)</versionRange> <goals> <goal>copy-dependencies</goal> </goals> </pluginExecutionFilter> <action> <execute /> </action> </pluginExecution> </pluginExecutions> </lifecycleMappingMetadata> </configuration> </plugin> </plugins> </pluginManagement>
 再到 project > build > plugins 裡面加入
<plugin> <groupid>org.apache.maven.plugins</groupId> <artifactid>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputdirectory>${basedir}/WebContent/WEB-INF/lib</outputDirectory> </configuration> </execution> </executions> </plugin>
