Keep Test classes in sync with Source classes - eclipse

In Eclipse, I have two source folders, one called src the other called test. They have the exact same package structure and each src Class has a test equivalent with "Test" appended to its name. Sometimes, I move my src classes during refactoring. Is there a setting where Eclipse automatically moves the test classes as well? Also, the same with renaming source classes.

No, because eclipse doesn't know the convention you are writing about.

Rename references at the same time in Eclipse

I have the following situation:
Consider that I have a class nested in a folder structure like for example /fol/der/exam/ple.java . Of course, the class ple.java contains package or import instuctions referencing to some sources. Now, when I choose Use as a source folder for /fol/der/exam/ple.java then, of course, the references used in package, import or function parameters are not the same anymore. I need to adjust them. Is there an elegant how to do that automatically in eclipse?
So, let´s assume that I have the following line in ple.java:
package fol.der.exam;
and that I have this line also in other files like a.java, b.java, etc. and I want to change the line, let´s say to package der.exam;
How can I do that automatically for all java files in eclipse?
best regards,

Newbie IDE (IntelliJ IDEA) issue: .class files not all usable

I'm working on a school project right now, and every time I have in the past, I always make a new Project in IntelliJ IDEA. However, this time she gave us some .class files that have methods in them that we can't see (she described what they do so we know how to use them) but need to use, so they have to be in the same folder, obviously.
SIDENOTE: I'm also new to using Macs, which is what I'm on at the moment.
Anyways, I put the .class files in my src folder that I found in the Project8 folder. I just made an array of the Book objects, which was one of the .class files I moved, and now I need to use a method from the other .class file, named BookInventory.class. I put that file in the src folder just like the other, but it won't let me use the only method in that class, which is LoadBooks.
Here is the LoadBooks signature:
public static void LoadBooks(Book[] b)
And here's the description of it that she gave to us:
"For each element in the array, accepts user input for the book, creates the Book object, and stores the object into the array."
So, when I made the array of Book objects, IDEA made an import statement up top all by itself, I didn't type it:
import java.awt.print.Book;
So why does IDEA recognize the Book.class file and allow me to use it in this .java file for my project, but it doesn't seem to notice the BookInventory.class file?
Any help appreciated, thanks ahead of time.
What is happening is when you first typed the line with LoadBooks(Book[] b), IntelliJ could not "see" your class files (you have subsequently loaded them in "class files" and added that as a project library, I presume).
IntelliJ however searched for and found a Book class in the internal java libraries, java.awt.print.Book. Note that this is a different class to the one your teacher gave you, which might have been e.g. edu.myschool.homework.Book.
Firstly, try to delete the line including the import statement, or manually change it to the correct package (your teacher can inform you what it is).
If the same import comes back automatically, you can go into Settings -> Editor -> General -> Auto Import and untick Add unambiguous imports on the fly - this will cause intellij to prompt you before adding imports.
Also, I would ask your teacher to give you the class files in a jar file, since that's the usual approach.
Good luck.

Creating Modelica Libraries

I have created a small Modelica library of my own. The way I have created it is in a single file. But I would like to make it a proper Modelica Library, as in the one with multiple directories for each subpackages.
So this is what i followed. File > New Modelica Class > Specialization - Package > Unchecked Save contents in one file. I copied the entire package code from the single file library, pasted it here and saved it. while doing so, I've noticed that the library lost most of its extends clauses, few models went missing.
Have I followed the correct procedure to create the library or did I do something wrong?
Can anyone point me towards the right direction?
#MSK, I cannot help you with OpenModelica as I work with Dymola. I did however recently split a single-file library (called package in Modelica) into several files manually. I did this so that the library hierarchy is represented in the file system hierarchy (i.e. several subfolders and .mo files in a library folder). For 35,000 lines of code this took roughly 10 hours. Just follow these steps:
create folder with same name as library
in this folder, create a text file "package.mo"
"package.mo" has to start with the statement
within ;
package [name of your package, i.e. the folder name...without the brackets];
now you want to create a subclass within this package. To do this create another folder containing a text file called "package.mo"
start this "package.mo" with
within [name of your package];
and declare the model as usual.
continue all the way down your library hierarchy
at the lowest hierarchy level you no longer need to create folders. You can simply create a .mo with the name of the lowest level class. As usual, start this file with
within [name of your package].[subclass1].[subclass2];
For an example of implementation please refer to the Physiolibrary found at https://www.modelica.org/libraries or the Modelica Standard Library which also uses this structure.

Is there a way to make IntelliJ IDEA *not* put Scala source files in their Java-style package directory?

In Java, you have to put source files in the directory structure corresponding to their package. foo.bar.Baz has to live in foo/bar/Baz.java.
In Scala, that requirement is relaxed. If all your classes in a particular project are in package foo.bar, you might just want them to live in the root source directory.
But IDEA flags this as an error, and forces me to put Scala classes in their Java-style directory when, for example, I copy or move classes. Is there a way to turn off this behavior?
Go Settings -> Scala -> Other settings -> Resolve to all classes, even in wrong directories.

Buildr: adding a path to the generated eclipse/idea files

I have a legacy java project that we have been moving to buildr/artifactory from ant/jars in svn.
The primary code is in the default (src/main/java) folder, but we have a few external source paths, for various tests that we can't move into the default folder, but we want to have access with it.
Currently, when adding a new library/regenerating IDE fields, it does not pick up these source paths, and I can't find a succinct discussion in the buildr manual for how to actually add them, rather than re-adding everything manually in eclipse (which just gets wiped out on the next regen).
Any idea how to have multiple source paths get picked up explicitly by buildr so that the idea/eclipse targets generate properly?
There are two ways that I know will work with IDEA. The second one might also work with Eclipse, while the first is specific to the idea task.
The IDEA-specific solution:
define 'proj' do
# ...
iml.main_source_directories << _('src/other')
end
iml also has test_source_directories and excluded_directories arrays you can append to.
The possibly eclipse-compatible solution, with more background than you probably want:
The iml object gets its default values for the main and test source directory arrays from project.compile.sources and project.test.compile.sources (slight simplification; resources are considered also). Buildr defines these .sources project attributes from the layout, so instead of explicitly appending to the iml attributes, you could use a custom layout for your project that includes your special source paths. That might work with the eclipse task, but I haven't tried it.
