目標org.apache.maven.plugins的執行default-deploy：maven-deploy-plugin部署失敗。 空指針異常

Question

運行命令時

如果我查看我的Maven回購，所有文件都已經通過構建上傳，如日志中所示（它說已上傳文件），但是最后構建狀態失敗，並出現nullpointer異常。 即使啟用調試模式后，我也不知道。 請幫忙。

升級到最新版本的maven-deploy-plugin為我解決了這個問題。

例如：

<build>
    <plugins>
        <plugin>
            <artifactId>maven-deploy-plugin</artifactId>
            <version>3.0.0-M1</version>
        </plugin>
    </plugins>
</build>
