maven2管理java项目和项目依赖

maven2管理java项目和项目依赖
我在开发项目中，遇到重用的代码比较多，特别是一些基类，工具类，每次都是拷贝过来使用，虽然也不麻烦，但是常常还是有不爽的地方，最近看到北京一个同事建立的项目有很多可以学习的地方。
把所有的基类、工具类都放置在一个叫easyapi的项目里面，它就是一个普通的JAVA项目，存放基类，输出就是一个jar包。
其他的WEB项目就可以直接导入这个JAR包来使用这些基类了。
我用MAVEN2来管理这些项目。

1、首先，建立一个叫easyapi的项目
src/java 存放JAVA的代码
src/test 存放TEST的代码
src/conf 存放配置文件，比如log4j.properties等，
以上三个目录都是在classpath下面的
POM文件pom.xml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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.sillycat.api</groupId>
<artifactId>easyapi</artifactId>
<packaging>jar</packaging>
<version>1.0</version>
<name>easyapi</name>
<build>
   <finalName>easyapi-1.0</finalName>
   <sourceDirectory>${basedir}/src/java</sourceDirectory>
   <resources>
    <resource>
     <directory>${basedir}/src/conf</directory>
     <excludes>
      <exclude>**/easyapi.properties</exclude>
     </excludes>
    </resource>
   </resources>
   <testSourceDirectory>${basedir}/src/test</testSourceDirectory>
   <testResources>
    <testResource>
     <directory>${basedir}/src/conf</directory>
    </testResource>
   </testResources>
   <plugins>
    <plugin>
     <artifactId>maven-compiler-plugin</artifactId>
     <configuration>
      <source>1.5</source>
      <target>1.5</target>
     </configuration>
    </plugin>
   </plugins>
</build>
<dependencies>
   <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>3.8.1</version>
    <scope>test</scope>
   </dependency>
</dependencies>
<scm>
   <connection>
    scm:svn:http://www.sillycat.com/repos/easyapi
   </connection>
   <developerConnection>
    scm:svn:http://www.sillycat.com/repos/easyapi
   </developerConnection>
   <url>scm:svn:http://www.sillycat.com/repos/easyapi</url>
</scm>
</project>
执行mvn clean install
可以看到其中的配置
<groupId>com.sillycat.api</groupId>
<artifactId>easyapi</artifactId>
<packaging>jar</packaging>
<version>1.0</version>
install之后会在我们的MAVEN2仓库中生成如下文件：
[INFO] Installing E:\work\easyapi\target\easyapi-1.0.jar to C:\Documents and Set
tings\Administrator\.m2\repository\com\sillycat\api\easyapi\1.0\easyapi-1.0.jar

2、生成WEB项目引入以上工具类
生成WEB项目的目录结构类似
只是在pom.xml中加入了导入以上api的jar包的东东
<dependency>
<groupId>com.sillycat.api</groupId>
<artifactId>easyapi</artifactId>
<version>1.0</version>
</dependency>
整个pom.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<project

3、在UBUNTU上执行easySOA的mvn install报错如下：
