您错过了 Apache common-compress 依赖项。关于您正在使用的构建自动化工具，您可以将其包含为:

Maven 依赖:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-compress</artifactId>
    <version>1.14</version>
</dependency>

Gradle /Grails:

compile 'org.apache.commons:commons-compress:1.14'

Jar 文件:

如果你需要这个jar，你可以从Here下载它。
