maven pom添加本地jar依赖，添加：

<scope>system</scope>
<systemPath>${project.basedir}/lib/EIESmProxyApi.jar</systemPath>

另外解决方式：

通过 maven-install-plugin 插件对 jar 包进行安装。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-install-plugin</artifactId>
  <version>2.5.2</version>
  <executions>
    <execution>
      <id>install-demo</id>
      <phase>clean</phase>
      <configuration>
        <file>${basedir}/../lib/demo.jar</file>
        <repositoryLayout>default</repositoryLayout>
        <groupId>com.demo</groupId>
        <artifactId>demo</artifactId>
        <version>1.0</version>
        <packaging>jar</packaging>
        <generatePom>true</generatePom>
      </configuration>
      <goals>
        <goal>install-file</goal>
      </goals>
    </execution>
  </executions>
</plugin>
