This Tip sounds very basic, but still: I get asked about this about once a week. So it must be something non-obvious in Eclipse then ;-): how to add existing files to an Eclipse project. As with many things in Eclipse, there is not a single way to do something. There are two basic ways to do this:
Drag & Drop
Copy & Paste
The first is the ‘official’ way in Eclipse, the other two are much faster and easier :-).
To import one or multiple files, select the folder/project where I want to add the files, then use the menu File > Import:
Eclipse has a great user interface (UI). But what if I want to do things from the command line, without the GUI? For example to build one or more projects in the workspace without using the Eclipse UI? With this, I can do automated check-outs and do automated builds.
Performed a command line project build with Eclipse
P&E has just released a new version of their Eclipse plugins for the set of GNU ARM Eclipse debug plugins. The GNU ARM Eclipse plugins from Liviu support OpenOCD and Segger J-link, so with this update or extension it adds P&E support to it. With this, I can use the P&E debug devices (P&E Multilink, Tracelink) or as well the Freescale OpenSDA with it.
One really cool thing with Processor Expert is: it does not only generate the source code for me, it generates as well documentation :-). I’m a believer of the ‘single source’ approach: if I have to document a software project, then the software itself shall be the source of the documentation. And for this I love Doxygen: see “5 Best Eclipse Plugins: #1 (Eclox with Doxygen, Graphviz and Mscgen)“. Doxygen is a compiler which compiles my source files, and instead of object files it creates documentation files for me :-).
Eclipse is not the fastest and snappiest IDE of the world, but in my view the most versatile and open one. And as with any tool: using it the wrong way does not make it better. Sometimes I have students in my classes which complain that Eclipse is slow, even on a decent machine. Looking at their notebook screens and Eclipse workspace usually tells me right away what they are doing ‘wrong': there are many, many projects open in the workspace, the most I have seen was more than 50 projects (yikes!!!)!
Eclipse projects have the nice features that they can link to files and folders: so instead of having the physical file, it is just a pointer to a file. This is very cool as that way I can point to shared files, or keep files in a common place referenced from projects, and so on.
Linked Folder and File in Eclipse
As with most things in Eclipse, there is not a single way how to do things. So I’m showing in this post several ways how to link to files and folders.
