I have installed NetBeans 7.3.1 on Mac OSX 10.8.4 with scala.
Could not load definitions from resource scala/tools/ant/antlib.xml. It could not be found.
init:
deps-jar:
/Users/.../NetBeansProjects/ScalaApplication2/nbproject/build-impl.xml:405: The following error occurred while executing this line:
/Users/..../NetBeansProjects/ScalaApplication2/nbproject/build-impl.xml:238: Problem: failed to create task or type scalac
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any / declarations have taken place.
BUILD FAILED (total time: 0 seconds)
I have added J-Dscala.home=%SCALA_HOME% to the netbeans.conf file
and on the mac terminal
echo $SCALA_HOME
gives
/usr/local/Cellar/scala/2.10.1/libexec
where
lib directory lives.
The netbeans error message could be worded more clearly.
One issue is that you are using MS Window's syntax %SCALA_HOME% for evaluating your environment variable. The Unix syntax is $SCALA_HOME or ${SCALA_HOME}.
The following works for me:
First add the following line to .profile
export SCALA_HOME=/usr/local/Cellar/scala/2.10.1/libexec
and append the following to netbeans_default_options in netbeans.conf
-J-Dscala.home=/usr/local/Cellar/scala/2.10.1/libexec
I'd prefer to just list the scala home directory in one place to make upgrades more foolproof, but referencing ${SCALA_HOME} from netbeans.conf didn't work for me. Maybe the environment variable needs to be defined elsewhere to be visible from netbeans.conf

I'm trying to use OProfile on Eclipse (3.8). The Juno version of oprofile didn't work, so I installed the Luna one. This one at least starts up, but can never find the libraries.
Here is the error:
ns3-dev-lena-profiling-debug: error while loading shared libraries: libns3-dev-lte- debug.so: cannot open shared object file: No such file or directory
profiled app exited with the following status: 127
I know that that means I need to add the library path. So I went to Profiling Tools Configurations, and specified the path under environmental variables as:
name: LD_LIBRARY_PATH
value: {workspace_loc:ns3dev2}/build (appended)
I manually checked and the library is located in the build folder. Furthermore, this library path works fine if I debug the same project instead (or run it...).
I've deleted the configuration and remade it, but it's the same error.
I also tried adding the same path to PATH instead of LD_LIBRARY_PATH, but that doesn't make any difference. (Just tried it for the hell of it).
Any thoughts?
Edit, I get the same problem on Eclipse 4.4 (Luna). I found the logs for the errors and the error is:
!ENTRY org.eclipse.linuxtools.oprofile.core 4 0 2014-10-27 12:33:07.200

I am running Ubuntu 64bit version, and downloaded the latest 64bit Eclipse.
Installed g++ along with build-essential. Tested g++ to make sure it works from terminal, and it works fine.
alex#ubuntu:~/Desktop$ g++ test.cpp -o test
alex#ubuntu:~/Desktop$ ./test
Hello World!alex#ubuntu:~/Desktop$
However, trying to build simple C++ Hello Word project(one of the default projects that comes with Eclipse), I am getting error.
Description Resource Path Location Type
Program "g++" not found in PATH Preferences, C++/Build/Settings/Discovery, [CDT GCC Builtin Compiler Settings] options C/C++ Scanner Discovery Problem
I have added Environment variable named g++ with value /usr/bin/g++ and the above error went away, however, now I am getting unresolved errors, though project compiles and in the Console shows !!!Hello World!!!
Description Resource Path Location Type

Have I correctly entered Environmental variable ?? How can I get fix the "unresolved" error ?? Thanks !
When compiling there are two important things to consider:
1.) Is my path up-to-date with executables?
2.) Is my library path correct?
It appears you satisfy 1.) but not 2.)
The unresolved symbol error means that Eclipse cannot find your library via LD_LIBRARY_PATH or some other medium. It's attempting to locate the standard compiled C++ library.
How did you install g++?
Kindly do this and post the results:
Project > Properties > C/C++ Build > Environment
If everything there appears nominal, you can try
/sbin/ldconfig
which should hopefully re-parse your system library paths and might update your environment.
On ubuntu 11.10 I installed eclipse from repositories, installed adt and cdt plugins. I am able to compile the hello-jni example using command line, but i would like to use eclipse for the task.
I followed the guide here: http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ and defined a PATH variable in eclipse preferences (window->preferences->c/c++->environment), pointing to the ndk-r7b folder. But the project won't buid. I get this error:
(Cannot run program "ndk-build"
(in directory "/home/athos/android/ndk-r7b/samples/hello-jni"):
java.io.IOException:
error=2, File o directory non esistente)
(last line should be "no such file or directory" in english)
If I specify "${PATH}/ndk-build" or "/home/athos/android/ndk-r7b/ndk-build" as the build command. i get this:
/home/lavoro/android/ndk-r7b/ndk-build
ERROR: Cannot find 'make' program. Please install Cygwin make package
/home/lavoro/android/ndk-r7b/ndk-build: 40: dirname: not found
or define the GNUMAKE variable to point to it.
If I define the GNUMAKE variable in window->preferences->c/c++->environment i get this:
ERROR: Your GNUMAKE variable is defined to an invalid name: /usr/bin/make
Please fix it to point to a valid make executable (e.g. /usr/bin/make)
Which is funny, since It suggests the exact same directory I indicated. Make is installed and present at the indicated location.
What am I missing?
It's a bit ugly, but you can always put
/fully/qualified/path/to/ndk-build
In your build command.
I have the following class and unit test in a PHP project in Eclipse:
I know my unit test works as I can run it at the command line:
Now I want to run this test from Eclipse. I set up PHP Unit in Eclipse like this:
However, when I run the PHPUnit tests:
It tells me that it can't include the class file:
/usr/bin/php -c /var/folders/UA/UAv38snBHd0QMgEPMCmM9U+++TM/-Tmp-/zend_debug/session4910937990995915704.tmp -d asp_tags=off /Applications/eclipse/plugins/org.phpsrc.eclipse.pti.tools.phpunit_0.5.0.R20101103000000/php/tools/phpunit.php --log-junit /var/folders/UA/UAv38snBHd0QMgEPMCmM9U+++TM/-Tmp-/pti_phpunit/phpunit.xml /Volumes/data/domains/et/extjslayout/phpunittest/tests
PHP Warning: include_once(../Product.php): failed to open stream: No such file or directory in /Volumes/data/domains/et/extjslayout/phpunittest/tests/ProductTest.php on line 3
PHP Warning: include_once(): Failed opening '../Product.php' for inclusion (include_path='/usr/local/PEAR') in /Volumes/data/domains/et/extjslayout/phpunittest/tests/ProductTest.php on line 3
PHP Fatal error: Class 'Product' not found in /Volumes/data/domains/et/extjslayout/phpunittest/tests/ProductTest.php on line 9
Why would PHPUnit be able to find the class when run from the command line but not when run from Eclipse?
When you start something from the command line, the "current directory" has a well-defined meaning: It's the directory where you started the command.
In Eclipse, what is the "current directory"? It's probably the directory from which you started Eclipse or maybe the folder in which Eclipse is installed.
I haven't used PHP in Eclipse before but for other languages, I can set the current directory in the launch config somewhere. If that doesn't work, define a variable which points to your project and then use absolute paths (using that variable as a starting point).
Have same problem. Found only solution by creating tests with internal PHPUnit wizard like at this screenshot:
Source: HowTo create a Test Case Class from a PHP Class
But following investigate show that your test case file should contain reference to tested code for example like this: require_once 'C:\Apache2\htdocs\jobeet\src\Ibw\JobeetBundle\Utils\Jobeet.php';
Other experiments with plugin config not bringing luck. So in my opinion PHPUnit from PHP Tools not well developed plugin. Consider using MakeGood plugin as better alternative.
orig post:
Hello List,
I am new to Java, Netbeans, and the IB Java API.
I downloaded the IB Java API software and I am using Netbeans to look at it.
On one of the files, Netbeans is indicating a problem with the file.
At the very top of the file, the author has placed a package declaration:
package samples.rfq;
Netbeans is using a red-dot to the left of the package declaration to tell me that it has a problem with the package declaration.
When I mouse-hover the package declaration, Netbeans tells me this:
Incorrect Package (Alt-Enter shows hints)
On my Mac-keyboard I press Alt-Enter and Netbeans just interprets that as an Enter (and then I need to undo that Enter).
I have 2 questions:
How do I work around the Alt-Enter-bug to see the hints?
What do you typically do when Netbeans indicates 'Incorrect Package' on one of your package declarations?
My comment to Josefx:
josefx,
I think maybe you gave me a good clue.
I looked at the file and I see it here in the (Linux) file system:
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$ ls -la /pt/z2/api/samples/rfq/SampleRfq.java
-rw-r--r-- 1 a a 14475 2008-08-13 15:49 /pt/z2/api/samples/rfq/SampleRfq.java
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$ grep package /pt/z2/api/samples/rfq/SampleRfq.java
package samples.rfq;
a#z2:/pt/z2/api$
So obviously it is in a directory which matches its package declaration.
I tried running javac against the file from a variety of directories.
This works:
cd /pt/z2/api/
javac samples/rfq/SampleRfq.java
If I run javac from any other directory it fails.
So, I see a dependency between 3 things here:
Location of the SampleRfq.java
Syntax in the package declaration
Location of the javac command
Since I got javac to work, I'm convinced of 2 things:
SampleRfq.java is in the correct directory
Syntax in the package declaration is correct
So, it looks like my issue is with Netbeans.
Netbeans is too ... 'stupid' to know that:
SampleRfq.java is in the correct directory
Syntax in the package declaration is correct
How do I help Netbeans?
I posted a question to the Netbeans mail-list and the only answer I got was: "Fix the incorrect file name".
ok,
I got the error to evaporate.
steps:
abandon my netbeans project
rsync my code to a new directory; create new NB project; (NB will not let me use old code)
right-click-project: select properties
Add folder
Pick the parent of the directory corresponding to the package
Netbeans now "knows" that the package declaration matches the directory structure.
