How do I refer to files generated by a sourceGenerators sbt task? I know that the source file is deposited to target/scala-<version>/src_managed/path/to/File.Scala but I don't know how to reference it in my project. Any ideas?
/server
/app
/models
Driver.scala (can't use MyGeneratedCode here)
/project
/src/main/scala/
ModelGenerator.scala (the code used to create MyGeneratedCode.scala)
/target/scala-2.12
/classes
/src_managed
/main/generated/
MyGeneratedCode.scala
The generate file works as any normal Scala file but on a fancy folder so it is not tracked by git (or any other VCS).
As any Scala file, it should had a package whatever statement at the beginning, from which you can latter import your classes (import whatever._). Usually the package name matches the directory structure, but they do not have to (specially since it is just generated file).
If it does not have a package, all its members probably resides on the __root__ package. But that probably would cause troubles, I would suggest editing your generator to add a package statement instead.

I'm a CS student and am in way over my head for an end of the year project, for which I need to find the dimensions and locations of a separate window. I've found that I need to use JNA libraries and understand how to do that but I don't understand how to import the JNA libraries through the manifest. Here is my file structure so far (I'm working in netbeans):
Project Folder
dist Folder
nbproject Folder
src Folder
Test Folder
Build.xml
Game.exe <-- This is the exe I run from the java file itself. I need to find this window's size and location for use later in the project
jna.jar <-- need to implement this as a classpath
Manifest.mf <-- I supposedly need to edit this.
The reason I show you this is to ensure that I've put the JNA Jar in the correct place.
Next, here is my manifest:
Manifest-Version: 1.0
X-COMMENT: Main-Class will be added automatically by build
Class-Path: C:\Users\justi_000\Google Drive\4. APCS\JZMinesweeper\jna.jar
So I need to edit the bit after the java -cp but I don't know what to put there, and in what order. The java tuts, etc aren't of much help.
Additionally, are these imports correct? They may be the problem and I have correctly imported everything, but I doubt that.
import com.sun.jna.*;
import com.sun.jna.platform.win32.WinDef.HWND;
import com.sun.jna.win32.*;
And, turns out, that it was a stupidly easy solution that my general incompetence caused me to miss.
Turns out it is actually possible to directly import libraries in IDEs...probably why they all include a tool for it. Blind old me has only ever used them once before (the perils of being a student) but we're all set. Simple as right click libraries>add jar.
Figured i would stick this here for future reference.
Using the really easy to follow instructions for building a NuGet package for an assembly with an associated package of sources for the symbol server, found here on David Ebbo's blog "The easy way to publish NuGet packages with sources" I have indeed created a pair of packages: binary and sources.
However, the sources package is incomplete and the reason is that the sources come from two class library .csproj and I used ILMerge to combine the results of the second into the first. (*) So, using the minimal .nuspec described in this post and pointing nuget.exe at the .csproj for the "main" library, the binary package is fine, but of course the sources package only has sources for the "main" library, not also for the library that was ILMerged into the "main" library.
How do I fix this (and get the sources for both projects included in the symbol package but only the binary for the "main" project in the binary package)?
FYI, the actual nuget.exe command line was: nuget pack CommandLineLexing.csproj -Build -Symbols -Properties Configuration=Release.
(*) The reason I'm doing this, in case you're interested, is that the second library is a cut down version of my accumulated "C# utilities" library - you know, a bunch of extension methods and other helpers - cut down so it only has the bare minimum needed for this particular project. And so, since it is cut down, I don't want there to be separate assembly for it which might eventually get confused with the full assembly (having the same name, and not a strong name). So I used ILMerge to put the utilities methods into the main assembly (and also mark them internal).
Not going to be easy I'm afraid.
NuGet symbol packages are simply your regular package, with pdbs, augmented with source files.
Assuming you already know you can get a merged PDB with ILMerge/ILRepack (/debug), that part is probably working file, I'm assuming your issue is that only the source files from the current project gets included.
You could simply post-process your symbol.nupkg (which is a zip), and include the source files from your other (merged) project in the src folder (you can even try that manually).
Though if you run srctool.exe -r MyMergedAssembly.pdb, you'll see different root paths, where usually (for a non-merged project) they all have a common prefix.
It may work, if SymbolSource copes with having multiple path prefixes in your PDB, that I haven't tried.
I also failed to find any documentation irt to their processing of symbol packages. We can assume they use pdbstr.exe tool to update the PDB srcsrv section of the PDB file to redirect the symbol loading to their website, but one can only tell if they support multiple roots by testing it.
If you upload your augmented symbol package to symbolsource, you can download the updated PDB using a URL similar to http://srv.symbolsource.org/pdb/Public/Castle.Core.pdb/4C81FC30DF584853B9869EAB2FA7D9891/Castle.Core.pd_ (then unzip it to a pdb file)
Then you can use both srctool.exe file.pdb and pdbstr.exe -r -s:srcsrv -p:file.pdb to verify their work.
My environment:
Netbean 6.9.1
Glassfish 3.0.1
Windows 7
Goal:
When my coworkers opens the Netbean Project, the library is already referenced without them manually create library, adding jars into it and reference it.
Detail:
I created Netbean project and the project has reference to few jar files in the folder.
Currently whoever opens the project for the first time, they have to manually create library and refer it to the project.
My project location:
C:\Users\masatosan\Desktop\myProject\myApp
My library location:
C:\Users\masatosan\Desktop\myProject\lib\myLib
The myLib folder contains:
some1.jar
some2.jar
some3.jar
I can achieve my goal if I create reference to individual jar file by defining to project.properties file like below: (creating reference to sqljdbc4.jar)
file.reference.sqljdbc4.jar=../lib/sqljdbc4.jar
javac.classpath=\
${libs.restlib_gfv3ee6.classpath}:\
${file.reference.sqljdbc4.jar}:
But my case is different since I have 3 jars in the myLib folder and wanting to reference them all.
Is it possible to reference all jars in myLib folder?
Please let me know if you need more clarification.
I'm sorry, but it doesn't work that way. When you create a project, you have to add the jar files individually.
However, if you put your lib folder under your project, netbeans will refer to them via relative paths. Then when you share the project (lib directory included), netbeans will be able to automatically find the jar files when the next person uses the project. That way you only have to add jar files once.
Short of using a dependency management tool like maven (which Netbeans has good support for), this is really the best solution. It uses a bit more disk space (obviously), but that's never been a huge issue for me.
I figured how so let me share.
Tool --> Library then library window pop up.
Create library called "MyLib" which contains multiple jars.
Add "MyLib" to your project. This change will be written to project.properties file under nbproject folder.
project.properties file indicates the classpath of lib reference you just added.
It should look like something below
javac.classpath=\
${libs.Excella.classpath}:\
${libs.MyLib.classpath}
Now someone else opens the project from different machine and she just needs to do step#1 and #2, which is to create library with same library name i.e. "MyLib"
I think this is what Bill was saying originally but thought it would be helpful to give step by step instructions since I finally figured .... after long time :D
Trying to understand how EDE works by using it to generate Makefiles for
a project directory that contains several targets under a specific
hierarchy. I'm not having any luck, and the info pages don't seem to
answer my question.
My directory structure looks something like:
(The asterix (*) marks files containing main() functions)
research/
flow/
flow.cpp
flow.hpp
program.cpp *
samples/
sample1.yuv
utils/
yuvreader.cpp
yuvreader.hpp
tests/
yuvreader_test.cpp *
I want to create EDE project(s) with one or more subprojects; or maybe I
just want one or more targets...?
flow's program.cpp requires flow/ and utils/ sources, but yuvreader_test
only requires utils/ sources.
I did ede-new in the root directory, and all subdirectories. I also did ede-new-target in the root directory, but when adding source files in subdirectories, it does not recognize the target I created.
I would appreciate it if someone could point me to some more complicated
Project.ede files for something like I'm trying to do. You can guess
that I have more subdirectories containing class code files, some of
which have standalone programs that use that code; also I have more test
code under tests/. Any example files/command workflows would be
appreciated.
The EDE feature that will generate Makefile or Automakefiles has a few more constraints than either Make or Automake. For example, the files belonging to a target must be in the same directory as the project containing the target. In your example, you would probably have no projects in your root directory.
To bring multiple sources together into a single program, a simple mechanism is to have each subdirectory create an archive (.a) or a shared lib (.so) that is linked together in your program.
If that is too constraining, you can also write your own automake files, and EDE will read those directly, so you can have a more complex build procedure as needed.
The CEDET distribution uses EDE as its build process, so you could look at that as a complex example. It doesn't build C++ files though, so it may not be as helpful as you would like.
I have a GWT project in eclipse with the following structure for the GWT module
com.foo.gwt -> Dashboard.gwt.xml
com.foo.gwt.client
com.foo.gwt.server
I have different packages com.bar.baz1, com.bar.baz2, etc. whose contents I want to include in client side code. All the files are GWT JAVA->JS conversion compatible.
The problem is that the <source> tag in Dashboard.gwt.xml, treats the path as relative to the directory of Dashboard.gwt.xml. So I cannot reference anything outside com.foo.gwt hierarchy.
So I created a new module MyNewModule.gwt.xml in com.bar and included baz1 and baz2 sub packages using relative paths in tag. Finally I made Dashboard.gwt.xml to inherit the new module.
This works fine when I compile the Dashboard module but fails when I compile MyNewModule.
That's because some classes in MyNewModule reference classes of Dashboard module.
I tried inheriting Dashboard module in MyNewModule. This creates a circular reference, but GWT doesn't complain about it. Everything works but I am not comfortable with the circular reference. I don't need MyNewModule, all I need is a way to include code from packages outside Dashboard module's hierarchy.
I am wondering why GWT does not allow absolute source paths.
Am I missing something here?
You dont need to compile each module separately. When you compile your com.foo.gwt project, GWT compiler will look for all dependencies in your com.foo.gwt.xml file and will compile ALL .java files both your com.foo and com.bar.baz. (and other libraries) to javascript.
As you said, its correct to put MyNewModule.gwt.xml in the com.bar.baz project and "inherit" it in your DashBoard.gwt.xml file. The part you are missing is to make a .jar file with MyNewModule project and put in war/WEB-INF/lib folder (just gwt.xml file and compiled java classes).
