1. 描述
   使用Maven打包時，總是會出現警告，原因是我引用了本地lib包導致。

D:\workspace\f>mvn package

2. 分析
   systemPath被設計用來講一些系統庫包含進來，它們往往具有固定的路徑。當在自己的project中使用這個特性但是指定相對路徑如${basedir}/src/lib之類的，就會提示這個。通過網路搜尋，發現解決的方案還是有的。

3. 解決方法
   方式一、將basedir修改為pom.basedir
   推薦使用方式一，簡單方便程式碼不多。

<dependency>
            <groupId>org.jbarcode</groupId>
            <artifactId>jbarcode-0.2.8</artifactId>
            <version>0.2.8</version>
            <scope>system</scope>
            <systemPath>${pom.basedir}/web/WEB-INF/lib/jbarcode-0.2.8.jar</systemPath>
        </dependency>
 

方式二、安裝到倉庫中

如下所示：

    <dependency>
            <groupId>org.jbarcode</groupId>
            <artifactId>jbarcode</artifactId>
            <version>0.2.8</version>
        </dependency>

        <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-install-plugin</artifactId>
                <version>2.5.2</version>
                <executions>
                    <execution>
                        <id>install-external</id>
                        <phase>clean</phase>
                        <configuration>
                            <file>${basedir}/web/WEB-INF/lib/jbarcode-0.2.8.jar</file>
                            <repositoryLayout>default</repositoryLayout>
                            <groupId>org.jbarcode</groupId>
                            <artifactId>jbarcode</artifactId>
                            <version>0.2.8</version>
                            <generatePom>true</generatePom>
                        </configuration>
                        <goals>
                            <goal>install-file</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
