Custom Code deploy error Class can not be used in custom code deployment

Question

Hello,

I am using https://github.com/shephertz/App42_CustomCode_Sample

After writing my custom code, I am trying to deploy it.
Although the sample provided worked fine, I cannot upload my code because :

Exception in thread "main" com.shephertz.app42.paas.sdk.java.App42BadParameterException: {"app42Fault":{"httpErrorCode":400,"appErrorCode":1900,"message":"Bad Request","details":"Class can not be used in custom code deployment java.lang.System : in source com.myCompany.myApp.Server.Helper.AntHelper"}}

at com.shephertz.app42.paas.sdk.java.util.Util.multiPartRequest(Util.java:344)

at com.shephertz.app42.paas.sdk.java.customcode.CustomCodeService.deployJarFile(CustomCodeService.java:84)

at com.myCompany.myApp.Server.Helper.AntHelper.upload(AntHelper.java:20)

 

The error description doesnt help me much...
What are the conditions to be able to upload custom class to app42 backend ?

Answer 1

java.lang.System class is not allowed to be used inside Custom Code.

Can you please let me know for which purpose you are using this class? Probably I can suggest some alternate to do this.

This came from the sample I used.
java.lang.System is used in AntHelper to log a few things.
And I was mistakenly putting this class into the jar I was trying to deploy.

I also came to realize that the package name for my custom code has to start with :
com.shephertz.app42.paas.customcode.... or it will refuse to deploy it.
