I have a quite complex ant build system comprised of many build.xml files in different folders. I want to crack on it.
Is there any IDE support (in Eclipse or Intellij) for me to jump to target definitions, taskdefs' definitions, macrodefs' etc.?
Besides "ant -v", any other way to ease the understanding of the flow of target execution?
Thank you.
In 2007, I wrote an article on the options to display Ant targets and dependencies visually. I think they will still work. I also had to deal with a large Ant codebase and the visualization really helped. (I used a tiny Ant build for the article but the tools do scale well.)
The default eclipse distribution contains an Ant XML Editor which helps navigating Ant files. Simply right click the Ant file and select "open with -> Other -> Ant Editor".
You can jump to target definitions by pressing CTRL and clicking on it. You can also set breakpoints in your ant scripts. If you start the ant script in debug mode from eclipse, execution will stop at your breakpoints and you can debug your ant script like you would any other code.

Usually when we use Eclipse IDE, it can assist us with related functions/variables, checking the compilation errors automatically.
Now I want to use Ant to manage the compilation and deployment process. After adding import instruction in build.xml, I can compile and run it with an Ant builder. But the problem is, when coding, the Eclipse editor cannot give code suggestions and always complains that I don't import some libraries which added in build.xml.
How to make the Eclipse editor give code suggestion and checking compilation errors based on settings in build.xml with a ant builder?
My version of eclipse works fine for code completion and syntax checking. Maybe yours is turned off? Check under Window > Preferences > Ant > Editor and then on the Problems tab make sure that 'Ignore all buildfile problems' is turned off.
There are also some content assist options around that area - mine are all turned on.
I'm using SCS 2.5.0.RELEASE, which sits on top of eclipse 3.6.1.r361
Is there any role for the Project menu when working with StatET and Eclipse using Sweave and R?
If so, are there any learning resources that explain how this might work?
Do these menus offer anything over and above a makefile?
I'm curious to learn more about building moderately complex Sweave/LaTeX/R projects.
Specifically, the Project menu has options Clean... and Build Automatically which intrigue me.

Hi Jeromy, I never managed to properly setup R and Eclipse, so I will only give you a partial answer.
Generally the Clean command is used to remove the compiled files from a project, so I assume it will delete any .ps or .pdf file generated by Eclipse.
The Build automatically setting (which is an on/off switch) rebuilds the project every time you save a file.
As a side note, to generate reports I use the combo LyX + Sweave that works very well. And for R scripts I find Gedit + RGedit nice and lightweight.
I don't know the internals of Eclipse very well, but I think these menu items are there for generic Eclipse projects that can link to the utilities that build your 'project' from 'source'. Looking under Project > Properties > Builder shows one builder configured, 'R Internal' that is not configurable or editable.
Personally I've never used a makefile for Sweave document creation, instead using the External Tools menu to setup the process for building a sweave Rnw file into a PDF. (under Run > External Tools > Configure External Tools. Also see here). This has worked well for me.
Have you considered asking your question on the StatEt mailing list ?
I am new to eclipse and wanted to do the following:
Use my custom build commands with eclipse. Until now I only saw make all. I use a shell script for building my project; how can I use that in an Eclipse environment?
When I create a new project with the existing source code, it doesn't add the files, without building the code and if code fails to build (because I generally don't have make all).
How do I resolve this issue?
You can add a custom builder in the "Builders" category of the project properties.
project->properties->builders->new
there you can also deactivate the default eclipse builders..
hope that helped
In addition to what smeg4brains said and assuming that you are using the CDT plugin you can go to:
project -> properties -> C/C++ Build
Uncheck Use default build command on the Builder Settings tab and replace make with e.g. scons.
On the Behaviour tab you can then specify the target to call for the Build and Clean phase.
To resolve your second issue open the Project menu and uncheck Build automatically.
This will prevent Eclipse from building the project when it thinks it is necessary.
If you want to add other your own commands then the easiest way is to write Ant file for your project so by clicking once you can execute all your commands.To see how to write Ant file click here
I was able to do something similar to have protoc run on my .proto files. I did it by adding a "Make Target" to the project.
A lot of stuff in Eclipse you can get around using Ant, which are XML scripts, and there is also a ANT project builder which uses those. If you don't like to mess with frankly quite touchy GUI options, just write a build.xml and use ANT build as the project builder.
After every save I need to right-click on the project in the project browser and click on build.
Is there a way to configure NetBeans to auto-build the project when I save a file?
See Compile on Save FAQ: http://wiki.netbeans.org/FaqCompileOnSave
I don't use CoS myself, I highly recommend Jenkins for your auto-build needs (and so much more): http://jenkins-ci.org/
The compile on save option is not available for free-form projects as of NetBeans version 8.0. And I don't think it will be made available in future too. The very idea of free-form is that that IDE does not know anything about your project and completely relies on the ant-scripts and the mappings you provide.
If you don't want to build an entire project every time you make changes to a file, create a target in ant to compile a single file and map it to the IDE command compile.single. You could add a context menu for that if required, although the existing keyboard shortcut F9 should suffice.
You can read more on the advance free-form configuration here - Advanced Free-Form Project Configuration
I have a set of dependent projects in Eclipse, each with its own Ant build script. If I make a change in multiple projects, then select "Build All" (Ctrl+B), each Ant build is invoked in the correct order. But if there is an error in one project, Eclipse still tries to build the other projects also, and in the process clobbers the Ant console so that the build errors are no longer visible. This wouldn't be quite so annoying if I could open up the offending project and select "Build Project", but Eclipse out-smarts me: it won't rebuild until I open some file in the project, edit it, and save (typically I add and remove a space character wherever my cursor happens to be). An answer to any of the following questions would be welcome.
How can I configure Eclipse to (in preference order):
terminate a "Build All" as soon as any project's Ant build fails?
save all console output for "Build All" instead of resetting the console for each project?
spawn a separate console for each new instance of Ant?
allow me to force a "Build Project" even if it doesn't think anything has changed?
[UPDATE] Bonus Question:
How can I configure Eclipse so that fixing any build errors in a depended-on project counts as a "change" for the purposes of "Build Project"?
Have you tried redirecting standard out to file via a run configuration? A few screen shots to help if not... (you may try 'append' this is not in my screen shot :) )
One alternative is to have each Ant build log itself, e.g., using the following in build.xml
<record name="build.log"
loglevel="verbose"
append="false" />
Oddly, Eclipse seems to disable this logging somehow when running an Ant build.
I am not too big on ant, but can't you make the builds dependent on one another?
