捕获异常：org.bouncycastle.asn1.pkcs.PrivateKeyInfo无法强制转换为org.bouncycastle.openssl.PEMKeyPair

Question

我正在尝试使用docker-maven-plugin（由spotify提供：https://github.com/spotify/docker-maven-plugin）使用Gitlab-CI构建一个docker镜像。

pom.xml

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <configuration>
        <imageName>MY_REGISTRY/${project.artifactId}</imageName>
        <imageTags>
            <imageTag>latest</imageTag>
        </imageTags>
        <dockerDirectory>docker</dockerDirectory>
        <resources>
            <resource>
                <targetPath>/</targetPath>
                <directory>${project.build.directory}</directory>
                <include>${project.build.finalName}.jar</include>
            </resource>
        </resources>
        <serverId>my-registry</serverId>
        <registryUrl>https://MY_REGISTRY/v2/</registryUrl>
    </configuration>
    <executions>
        <execution>
            <id>docker-build</id>
            <phase>install</phase>
            <goals>
                <goal>build</goal>
            </goals>
        </execution>
        <execution>
            <id>docker-push</id>
            <phase>deploy</phase>
            <goals>
                <goal>push</goal>
            </goals>
        </execution>
    </executions>
</plugin>

以下是带有maven debug的完整版本：

当我使用Jenkins时，我没有收到任何错误。

mvn clean javadoc:javadoc javadoc:test-javadoc deploy -Psonar sonar:sonar

在Gitlab-CI中，我将maven分为4个阶段：

• 构建
• 测试
• Code_Covergae
• 部署

部署阶段失败，我执行此命令：

mvn deploy  

我不知道如何解决这个问题，我们将非常感谢任何意见。
