RE: Compilation Error -Incompatible Types

[pradeepkumar]

Hi  David , 


This is the original post .

I am facing the compilation error in my Jenkins job. 

We are not getting compile time error in Eclipse for BusinessObject but we
are getting incompatible types error in Jenkins. 
Is there any way to resolve this issue rather than changing the source code. 


Please find the below. 

  
[ERROR] COMPILATION ERROR : 
[INFO] - 
[ERROR] /C:/Jenkins/jobs/XXX
Commons/workspace/src/com/ABC/XXX/bo/BusinessObject.java:[4158,102]
incompatible types 
  required: com.ABC.XXX.bo.BusinessObject 
  found:com.ABC.bo.BusinessObject 
[INFO] 1 error 
[INFO]  

Please help me out regarding this issue.

Maybe you are missing a library that is provided by  Eclipse for
BusinessObject  but not defined in the pom.

In that case you need to find that library and add it to your maven build.

RE: Compilation Error -Incompatible Types

[David Evans]

I'm afraid I know nothing of Jenkins so I'm not able to advise on changing that.

I was suggesting you might check the source to see which of 
com.ABC.XXX.bo.BusinessObject and  com.ABC.bo.BusinessObject was being imported 
 and confirm which one SHOULD be being imported.  It might be that a difference 
in classpaths is allowing you to get away with a source error in Eclipse but 
not elsewhere, so the fact that it works in Eclipse doesn't guarantee it's 
right.  It's a mistake I have made in the past.

If you are sure that the source is correct then my observation will not apply!  
Good luck either way. 

Regards

D.E>

That simply means your code is not Java compliant. It does not matter that 
the Eclipse compiler has no problem.

I'm not sure this is the case here, but most of the time differences
between eclipse and command line compilation are due to scopes problems.
Eclipse is merging various scopes (test/compile ..) when compiling while
command line is enforcing strict separation.
Have a look at the scopes of the libraries of both problematics objects.

Hi
Maybe try
- to avoid wildcard (*) in your imports statement
- check dependencies version differences between your workstation and
jenkins

I agree that Eclipse's handling of scopes is a common reason for code which
works in Eclipse, but actually fails on the CLI.

However, there are also significant differences in the compilers
themselves, which I have encountered quite frequently. In particular,
Eclipse tends to be laxer about complex generics expressions than javac is.

RE: Compilation Error -Incompatible Types

[David Evans]

I think the original question noted two different classes along the lines of

com.someone.xxx.bo.BusinessObject  and
com.someone.xxx.BusinessObject

These are different classes.

... I cannot find the original post and I can't be sure so sorry if this is a 
red herring.


One of Eclipse's useful features is to allow you to pick a missing class to 
import (as a "quick fix").

I have sometimes made the mistake of picking the wrong class from the list 
offered. 

If I pick java.awt.List instead of java.util.List things go wrong downstream 
quickly and the mistake is pretty easy to find.

If I pick a super or subclass of the one I should have chosen, the cause might 
not appear so quickly.  The Primavera Integration API, for example, provides 
ample opportunity to make this kind of error - where a "family" of classes can 
live in different jars.

Of the classes listed in the original post, which one should you be using? I 
would go back to my source and check whether the import is correct.  As others 
have alluded to, the fact that it "works" in Eclipse doesn’t necessarily mean 
it's "correct".

D.E.

Compilation Error -Incompatible Types

[pradeepkumar]

Hi ,

I am facing the compilation error in my Jenkins job.

We are not getting compile time error in Eclipse for BusinessObject but we
are getting incompatible types error in Jenkins.
Because there is difference in package for the reference BusinessObject and
the Object factory method returning. 


Please find the below.

 
[ERROR] COMPILATION ERROR :
[INFO] -
[ERROR] /C:/Jenkins/jobs/XXX
Commons/workspace/src/com/ABC/XXX/bo/BusinessObject.java:[4158,102]
incompatible types
  required: com.ABC.XXX.bo.BusinessObject
  found:com.ABC.bo.BusinessObject
[INFO] 1 error
[INFO] 

Please help me out regarding this issue.

Is there any was to resolve this issue from maven side by adding any flag to
avoid cast typing issues.

Just because Eclipse can compile it, does not mean that javac of Oracle JDK 
can also. You better try to compile from console using the real compiler to 
see what's wrong.
