Add how explanation of how to work with JPSG projects in IDE

[leventov]

On the other hand, IDE will think that there are duplicate classes in the project (because a template file's name (class name) and package are the same as in one of the generated specializations), so you will lose the ability to build the project from IDE (you will need to use Maven or Gradle every time to build the project).

In tutorial is false, because, at least in IntelliJ, there are "Delegate IDE build/run actions to Gradle (maven)".

This issue is about adding that information to the tutorial.

@leventov Really cool idea you have here. Regarding this issue, I do really want to use my template as the "real" class, so I've put the JPSG folder on the main classpath. To avoid creating duplicate classes I've done the following workaround:

/* with double|int type */
package com.x.y.z;
/* if int type */
...
/* endif */

That generates a blank file, except the package declaration, for the double type which is already covered by the template. This compiles, only puts one class in the .jar, and works with IDEs, but is a bit sloppy having two files with the same name.

What if there was a syntax like:

/* with double|int type except double */

which would allow you to find and use the double template, but essentially skip it in the matrix of things to generate.

Maybe this "skip" ability already exists and I'm missing it in the docs?

[leventov]

Did you try:

/* with double|int type */
/* if !(double type) */
package com.x.y.z;

It's described in the end of this section: https://github.com/TimeAndSpaceIO/java-primitive-specializations-generator#-if--blocks, just before the "define" section

@leventov that did it! thank you!
So, isn't this the primary use case? that you want to use your template as one of the real classes and generally want to skip it in the matrix of dimensions? If it was the default behavior to skip the template, and you had to force it to re-generate (instead of forcing it to skip with an if) wouldn't that avoid the IDE/compiler issues?

[leventov]

It was not like my original use-cases, because my templates are not quite 100% functional Java code, so I made the full generation behaviour as default.
