通过客户端用户代码部署将JAR上载到Hazelcast云后出现NoClassDefFoundError
我目前正在尝试Hazelcast云，我需要将jar依赖项上传到Hazelcast云服务器。我有大约20mb要上传，通过客户端用户代码部署功能上传似乎很好，但是一旦上传完成并尝试使用类，我就会收到这个错误。我正在使用Jet streams和IMDG地图、集合、列表和执行器服务。是否有些功能在Hazelcast Cloud上不受支持，或者我遗漏了什么？我在想，当以编程方式使用客户机用户代码部署功能时，我可能还需要通过客户端用户代码部署将JAR上载到Hazelcast云后出现NoClassDefFoundError,hazelcast,hazelcast-cloud,Hazelcast,Hazelcast Cloud,我目前正在尝试Hazelcast云，我需要将jar依赖项上传到Hazelcast云服务器。我有大约20mb要上传，通过客户端用户代码部署功能上传似乎很好，但是一旦上传完成并尝试使用类，我就会收到这个错误。我正在使用Jet streams和IMDG地图、集合、列表和执行器服务。是否有些功能在Hazelcast Cloud上不受支持，或者我遗漏了什么？我在想，当以编程方式使用客户机用户代码部署功能时，我可能还需要addClass，而不仅仅是addJar 下面是添加依赖项的代码 ClientUserC
