Can't compile repo about jacop HOT 6 CLOSED

Hi,

Did you use Maven to execute phases clean/compile/install of JaCoP? JaCoP is distributed as Maven project and those classes that are missing for you will be generated by Maven.

If you use Maven you should not have those compiler errors.

Hope that helps.

Hi Radek

Thanks for getting back to me, I imported the project into eclipse as a
maven project.
But running maven from the command line gives me the same problem:

$ mvn clean
$ mvn compile

... many more errors

Note: compiling with java 8.

Hi,

I downloaded master branch in zip form from github. I opened the project in InteliJ (this is the IDE I use) and I did clean/compile/install for JaCoP maven project. I did it with 1.7 Java. I do not have 1.8 version installed.

It builds successfully.

Thus, somewhere (Maven, Eclipse, Java 1.8) lies your problem. Not sure where. Usually, Eclipse and Maven projects are the first suspect. Can you run "mvn clean install" from the terminal window?

best,
Radek

P.S. We have a jar file available for download at Sourceforge if you have problems building yourself.

Hi
I recloned the git and run mvn clean install before I imported the
project into eclipse and it works. So thanks a lot for this.

I now have warnings that my eclipse settings turn into errors ( this is on
purpose to enforce certain rules ), for example:

1. File Alldiff.java
   public static String[] xmlAttributes = {"list"};
   -> this hides a field in the super class

2. File AndBool.java
   public void consistency(Store store) {
   -> add missing override annotation ( see Item 36 Bloch, "Consistenly use
   the override annotation )

I would suggest that 2) should be fixed as it seems to be a clearly
identified best practice.
I am less sure about 1) . Is my workspace compiler setting to strict or is
this something that could be improved upon in the code ? For example by
making xmlAttributes to protected ( rather than public) and reassigning
the string in the constructor of Alldiff + adding public getters ? What do
you think ?

Hi,

Thanks for persistence in solving your problems. It gives us some feedback what we can do better to make it easier for people to start with JaCoP. IDEs can be differently setup and your strict Eclipse setup is less forgiving than other IDEs.

Concerning remaining two warnings.

This xml attribute is not used, we were planning to use it for some xml support but then we dropped it so this code will most likely be removed in future versions. An item to clean up the code.

Override annotation is a pain. It has been changed somewhat between 1.5 and 1.6 version. I will recheck behavior for it in 1.6, 1.7, and 1.8 and if I can get rid of warnings in all three different Java versions then we will fix this issue too.

Thanks for feedback.

best,
Radek

Hi Radek
Thanks a lot for your support. In fact override annotation in eclipse is
really fun. You can select the packages that are missing overrides and then
right click "clean source". You can configure what "clean" means, but the
default setting will add overrides automatically where necessary. This is a
great feature.
Thanks again
Peter
