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,

I am using Modelica in my work, where I have modeled a system that contains many models. I want to make it simple to use by creating a package using " within" so this package contains all the models. What I want is to open the package instead of opening many models, which takes time.
Instead of doing everything by hand, I suggest to create your packages with a Modelica tool (OpenModelica, Dymola, SimulationX, ...).
The tool will automatically create the folder structure and the within lines in the .mo files for you. Doing it manually is not much fun.
You could e.g. use OMEdit (part of OpenModelica) to create your package structure as follow:
create your top-level package via File > New Modelica Class
insert sub-models and sub-packages in existing packages via right-click > New Modelica Class
According to this website http://omwebbook.openmodelica.org/
A package is simply a container or namespace for names of classes, functions, constants, and other allowed definitions. The package name is prefixed to all definitions in the package using standard dot notation. An import language construct is provided for Modelica packages.
the package can help us to gather components that build the main model together in same place inside it , just by clicking on the package you open all your components inside it.
to open a package in Modelica we follow the follwing instructions:
After creationg the package you will get a folder with the package name in the place that you chosed to saved it in it , when you open the folder you click on package in order to open your package .
hope this can be helpfull
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.
Please tell me a more describing title :P
I have an SBT project in IntelliJ and its src directory constructed like:
src/main/scala/package1/AAA.scala
src/main/scala/package1/BBB.scala
src/main/scala/package2/CCC.scala
src/main/scala/...
So now these classes are imported like:
import package1.AAA._
But actually I want to import these classes like:
import org.myname.package1.AAA._
At the moment I have two ways; one is to put org.myname to all the class files' package attributes like:
package org.myname.package1
class AAA {...
which works, but doing this manually is time consuming, and makes things complicated.
Another one is to reformat the directories like:
src/main/scala/org/myname/package1/AAA.scala
src/main/scala/org/myname/package1/BBB.scala
src/main/scala/org/myname/package2/CCC.scala
src/main/scala/org/myname/...
which works too, but I'd not like to make the looking of the structure like this.
Is there an automatic way to include all classes into org.myname without changing the structure, with the SBT or IntelliJ features?
Create a new package named org.myname.
Move the package1 inside org.myname
Move package2 inside org.myname
IntellIJ IDEA will fix everything for you.
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.
I have a properties file used for building in Ant containing variables that I want to add to Eclipse classpath. Is there a way to do this automatically?
Ideally I'd like to be able to add an argument to the command line and automatically import the values in the file.
Acceptable solutions also include the usage of a plugin that adds this functionality.
Example:
test.propeties
MW_HOME=C:\\Program\\Oracle\\
TEST_HOME=C:\\temp\\
