问题分析

解决方案

                <dependencies>
                    <!-- 使用4.4版本来混淆 -->
                    <dependency>
                        <groupId>net.sf.proguard</groupId>
                        <artifactId>proguard</artifactId>
                        <version>4.4</version>
                        <scope>runtime</scope>
                    </dependency>
                </dependencies>

注意，这里使用4.4版本的，有文章中使用4.8版本来混淆，但是在Maven的仓库中http://repo1.maven.org/maven2/net/sf/proguard/proguard/

找不到4.8的版本。
