Eclipse java project where directory structrure != package structure
This is not possible in Java, the runtime system always looks for a/b/c as directory structure for a specific class in package a.b.c. See http://docs.oracle.com/javase/specs/jls/se7/html/jls-7.html#jls-7.4

org.eclipse.core dependency to org.eclipse.runtime suddenly changed
The problem is likely caused by version ranges. These ranges do not even have to be used for the Eclipse artifacts. Assume you depend on [1,2) and 1.1, and 1.2 are available. At a moment in time, 1.3 is added that has different dependencies. If it finds multiple groupId:artifactId with a different version then it picks the first it finds. Maven follows a breadth first strategy to find dependencies so that you can override it in your top level pom. This is of course very obscure and error prone. A better way is to specify all your app dependencies in one pom so you can ensure valid versions.

Change project file structure after migrating from Eclipse to Android Studio gradle structure
While migrating your project from Eclipse to Android Studio, no change have been done on project structure. The only that have changed are new .iml and .gradle files. Your java code stays in project/src/ folder, and has not been moved in project/src/main/java folder (like in a new created project from AndroidStudio). Your AndroidManifest file also stays in the project/ folder and has not been moved in project/src/main/ folder (like in a new created project from AndroidStudio). At migration, the build.gradle file is customized in order to be able to compile with the old structure is described in the gradle documentation : Configuring the Structure For a new created project in AndroidStudio, the sourceSets part of the build.gradle file : sourceSets { main.java.srcDirs = ['src/java']

I used m2eclipse plugins in eclipse.why the imported package still cannot be resolved by eclipse?
First of all, you're not using the m2e plugin; while it may be installed, it's not activated for this project: There is no little "M" on the project's icon The classpath doesn't include an entry org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER From what I can see, Eclipse can't resolve the dependencies since the variable M2_REPO isn't defined (if it could, you would see the absolute path to the JARs in the upper image after the symbolic path). To fix this, go to Preferences and search for "Classpath Variables". Add M2_REPO there with the correct path (default is $HOME/.m2/repository). If it already exists, make sure the path is correct. Alternatively, right click on project and select "Convert to Maven Project" under "Configuration".

Can maven resolve local resources whose folder structure changed?
When you build the war, put src/main/resources into /target/resources instead of /target directly. THIS PAGE shows outputDirectory parameter which specifies the output folder for resources. I think it would look something like this: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <configuration> <outputDirectory>${project.build.outputDirectory}/resources</outputDirectory> </configuration> </plugin>

How do I structure my Python package?
You could use the second structure, but in your __init__.py, simply have... from .project import PublicClass1 from .project import PublicClass2 from .project import PUBLIC_CONSTANT_A ... Basically, only importing in __init__.py what you actually want to be public, while keeping __init__.py mostly free of code logic.

Trigger an event in Python traits package when an Array element is changed
I'm afraid that it's not really possible. numpy arrays view raw memory. Anything can change that memory without going through the numpy array object itself. The pattern we usually use is to reassign the whole array after doing the slice/index assignment. import numpy as np from traits.api import Array, HasTraits, NO_COMPARE class C(HasTraits): x = Array(comparison_mode=NO_COMPARE) def _x_changed(self): print 'Doing something' c = C() c.x = np.linspace(0, 1, 10) # This does not trigger: c.x[3] = 100 # This does: c.x = c.x

Android Studio Project Structure (v.s. Eclipse Project Structure)

Can't get EAR package structure correctly with Maven
Ok, after I checked out a project from various maven archetypes I found the error... the minimal error... it's always a minimal error costing huge amounts of time... In the dependencies section of the ear file, where I define my ejb as dependency, just add this: <type>ejb</type> so it's: <dependency> <groupId>at.betrieb.projekt</groupId> <artifactId>extended-ejb</artifactId> <version>1.0</version> <type>ejb</type> </dependency> Afterwards it works correctly. Obviously it is wrong on the IBM page and on many other pages. Besides I found out the following section is also outdated, and can be completely removed from the ear-plugin section: <jarModule> <groupId>at.betrieb.projekt<

Clarification in Java Package structure
No, they won't clash. If that was a problem, you couldn't use several libraries from, fo example, Apache at the same time, because they all put their classes under some sub-package of org.apache. You can see the package tree of all the classes in the classpath as a giant tree containing a merge of all the package trees of all the jars and directories listed in the classpath. If you had two classes with the exact same package and name in two different jars/directories in the classpath, then that would be a problem, because only the first one would be available, and you can't (AFAIK) have any guarantee about the order of the WEB-INF/classes and jars under WEB-INF/lib in the classpath.

A tool to validate the structure of a Python Package?
If you call a module using: python -m module Python will load/execute the module, so you should catch crude syntax errors. Also, if module has a block like: if __name__ = "__main__": do_something() It will be called. For some small self-contained modules I often use this this block to run tests. Given the very dynamic nature of Python, it is very hard to check for correctness if the module author is not using TTD. There is no silver bullet here. There are tools that will check for "code smells" and compliance with standards (dynamic languages tend to generate a profusion of linters). pylint PyChecker PyFlakes PEP8 A good IDE like PyCharm can help, if you like IDEs. These tools can help, but are still far from the assurance of static languages where the compiler can catch ma

How do I create a class with constant properties accessible to other classes within a package folder structure?
Are you sure you have "RootFolder" added on the path? Here is a quick test I did, which works just fine (I'm running R2013a): root/+pkg/MyClass.m classdef MyClass properties (Constant) Version = '1.0'; Info = struct('Name','MyClass', 'Version',pkg.MyClass.Version); end end Now >> addpath('/path/to/root') >> pkg.MyClass.Version ans = 1.0 >> pkg.MyClass.Info.Version ans = 1.0 So I was able to even directly index into the returned structure. Note that if you want to reference any of the constant properties inside other properties, you have to use the fully qualified name including the package name (just like we did for the "Version" property inside the structure)

In Eclipse, how can I export a package and all sub-packages as a jar?
Go to file->export->JAR file, there you may select "Export generated class files and sources" and make sure that your project is selected, and all folder under there are also! Also, make sure they are in the Build Configuration -> Order and Export area, and they are checked for export. If all else fails, try FatJar. It detects all dependencies and automatically bundles them into the JAR. In Eclipse you can use FatJar by using the Build Fat Jar option for Java projects.

How do I use PDFBox with Eclipse? Does it package in jar files?
You will need to send both the jar you produce (from building your project) and the PDFbox jar. The PDFbox far file must be in the CLASSPATH when you run your application. Add a jar (for the purpose of building only) as follows: select the project, type ALT-Enter (or right-mouse on the project and select properties), click on "Java Build Path", click the "Add External Jars..." button, browse to the PDFbox jar file, click the "open" button, then click the "OK" button (on the properties window). The PDFBox jar file is now in the build CLASSPATH of your project. See step run concerning the runtime CLASSPATH.

How to export an Eclipse builder (or package it) for Importing to other projects?
If you've implemented the builder using the New>Program sequence adding the program you're calling in that manner, then the simplest solution is use the same specifications and add an external tool configuration with the same definition (you may need to delete the definition from the original project builder tab). Once defined as an external tool, the tool can be imported using the import menu on the project builder tab.

For me the solution is to do a clean build before exporting the signed package. A clean build of project and libraries.

You probably didn't update your imports in your main file (the one who runs the main method). ClassNotFoundException implies that the classloader couldn't find a certain class given the current directives. Eclipse should be sending you a warning about this (underlining the offending imports in red). To organize the imports for a given file directly, use the Ctrl + Shift + O shortcut while editing it.

Things that aren't java classes but need to be in your classpath. If you put them under /java, they won't be copied into your classpath so you have to put them here. src/main/webapp This is for webapps. Everything you put in here will be copied over to your war file, directly.

Which preference controls whether multiple selection is available to Package Explorer in Eclipse?

To fix it, I simply disabled "Show position of pointer when the Control key is pressed"†. † On my Red Hat Enterprise Linux 6 installation this is located in: System > Preferences > Mouse > General tab, Locate Pointer section The thing which finally gave my a hint was identifying that this was probably due to the same underlying problem as another I was having with the NoMachine NX client, where the nxclient wasn't passing Ctrl key presses to the remote end at all.

How can I find an Eclipse update site of a specific class/package
I don't think that there is a general solution for this – I am not aware of any search engines for p2 repositories. So you will need to do manual steps. I'll start with the second one: Let's assume you already have the URL of a p2 repository (aka update site) that may contain the package you are interested in. How do you find out what the repository contains? One option is to try to read the p2 metadata files directly. These are located at <repositoryURL>/content.jar or /compositeContent.jar or /content.xml, or /compositeContent.xml. The metadata files are kind of human-readable: An (optionally jarred) content.xml lists all bundles and their exported packages, and you could do a string search for the package you are interested in. An (optionally jarred) compositeContent.xml

Eclipse QuickFix Crashes when Importing from java.util Package
Use Windows -> Preferences -> Java -> Editor -> Content Assist -> Advanced to disable proposals (in the upper list), especially if you believe those are from a third party tool. Also, code completion has a timeout. So if some suggestion engine in Eclipse takes too much time, it is terminated by the code completion UI. That again is normally indicated by a message box, so I assume this is not your problem. Lastly, you may want to check there is sufficient memory available in Eclipse. Otherwise the completion proposal processor may run into an out of memory and the thread is killed silently.

maven-archetype-webapp directory structure using Eclipse Kepler
After struggling about what was going on the archetype and for what reason it didn't create the usual structure...I decided -as a productivity workaround- to create a new maven project and skip archetype creation. After that I copied from an old project the directories of META-INF and WEB-INF and everything is working fine. I suggest if anyone reaches this point to just do the same in order to get going and not waste anymore time. If someone knows the solution I will be more than welcome to read it :)
