错误java.lang.securityException：清单主要属性的无效签名文件摘要

Question

我正在使用SendGrid API在我们的Java服务中使用SendGrid Maven依赖发送电子邮件。

<dependency>
        <groupId>com.sendgrid</groupId>
        <artifactId>sendgrid-java</artifactId>
        <version>4.9.2</version>
    </dependency>

我们创建一个胖罐子来执行它。 但是，在添加了此依赖性之后，Fat Jar并未执行，给出了SecurityException：无效的签名文件，

此处的堆栈跟踪错误：

因此，我们需要在创建胖罐时过滤签名的文件。
在maven shade-plugin中添加过滤器

                   <configuration>
                            <filters>
                                <filter>
                                    <artifact>*:*</artifact>
                                    <excludes>
                                        <exclude>META-INF/*.SF</exclude>
                                        <exclude>META-INF/*.DSA</exclude>
                                        <exclude>META-INF/*.RSA</exclude>
                                    </excludes>
                                </filter>
                            </filters>
                     </configuration>
