| Code Recommenders do not work for me [message #893767] |

I just installed the recent version of the Code Recommenders, but unfortunately it doesn't work for me (eclipse 3.7 or 4.2, doesn't matter).
The only working thing is Subwords content assistant.
I don't know, does it make sense, but .plugins\org.eclipse.recommenders.rcp is almost empty. Repository folder has the following subfolders:
.plugins\org.eclipse.recommenders.rcp\repository\org\eclipse\recommenders\index\0.0.0\
That's all I have in it.

Anything in these folders?
under .metdata/plugins/org.eclipse.recommenders.rcp there should be
/index/
(some index files in there)
/repository/org/eclipse/recommenders/index/0.0.0/
_maven.repositories
index-0.0.0.zip
index-0.0.0.zip.etag
I assume you have an internet connection as the search index will be downloaded/updated when Recommenders starts. Without an internet connection only the folder gets created. Also: Models are downloaded on demand (once), i.e., on first access. However to make this happen the index needs to be downloaded successfully before.
Is there anything in the logs?

empty as well
Quote:I assume you have an internet connection
yes, through the corporate proxy/firewall. At least Eclipse was able to download & install code recommenders via the Install feature 
Quote:Is there anything in the logs?
Nope.
Is there any way to enable kinda 'detailed log' or debug this somehow?

In the PDE error log view there should be at least two error messages
like those below:
Error log is empty.

Nope.

Checked.

Well, there is one more empty subdir - .plugins\o.e.r.r\repository\org\eclipse\swt\org.eclipse.swt.win32.win32.x86\3.0.0\

The same problem.
I just run code recommenders in debug mode and got the following:

No not directly.
But the simplest approach I can imagine that could work right away:
Find one of the mirrors that allows rsync on the models folder and copy/link everything below into you repository folder under .metadata/plugins
An alterantive would be to provide a test repository for download that can be extracted and used locally. I'll consider that for Monday. I'm travelling and won't have good internet access during the weekend.
In the meanwhile: I've triggered a build (build-id: b582) for recommenders which will be available on recommenders head update site in ~20 minutes [1]. It has a larger timeout value. Maybe one of you could give it a spin later today?

My guess that this is the proxy issue.
For instance, if I change
Response r = http.prepareHead(url).execute().get();
to
Response r = http.prepareHead(url).setProxyServer(new ProxyServer(MY_PROXY_ADDR, 8081)).execute().get();
then it successfully creates .plugins\org.eclipse.recommenders.rcp\repository\org\eclipse\recommenders\index\0.0.0\index-0.0.0.pom.etag
Well, no progress after that, but...

Great! As Eclipse comes with it's own proxy preferences we should reuse them for Recommenders' model repositories too. Could you open a bug for this in Bugzilla?
As you already have a working environment: If you'd like to finalize your hack and add support of proxy settings, I'd very much appreciate a patch in Gerrit

Srujan,
from your rar I can see that the network connection works fine. The index is downloaded properly. However, yet no model file gets downloaded.
Could you send me the java project you try to use Code Recommenders in? Maybe you use an unexpected configuration that prevents Recommenders from resolving the models of your Java Runtime. A Screenshot showing your project folder contents in the Package Explorer could also help.

Srujan,
after thinking about it for a while. Can you send me your project's .classpath file?
Resolving the model for all Java Runtimes independent of the underlying OS and exact classpath, we check the project's classpath for a classpath container named "org.eclipse.jdt.launching.JRE_CONTAINER". All jars below are mapped to the JRE model. It may be the case that your project uses a different name for this special container which would cause the lookup to fail.
To give an example, in my projects the classpath file looks as follows:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/>
<classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
<classpathentry kind="src" path="src"/>
<classpathentry kind="output" path="bin"/>
</classpath>

hey marcel,
Here is the contents of .classpath file.
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jdk1.7"/>
<classpathentry kind="lib" path="C:/Documents and Settings/sgulla/Desktop/Downloads/icu4j-4_8_1_1.jar"/>
<classpathentry kind="output" path="bin"/>
</classpath>
In the same project(as .classpath above), One more thing i noticed that, when I do a "java". and wait for content assist i do see the feature "Intelligent Code Completion" working meaning giving the most uses method of String class in this case(giving % usage like .equals - 41%, length -20%)
Even though I see "Intelligent Code Completion", still going to Preferences-> I see the jars to be "UNRESOLVED"

Hi Srujan,
you said code completion works but does not highlight the resolved model on the preference page, right?
As code completion on "string" worked - does the preference page still show UNRESOLVED for rt.jar?
Just to be sure we have the same understanding of what UNRESOLVED means: All jars will initially have the status UNRESOLVED. Models for these jars will be loaded lazily, i.e., when you trigger code completion on any of the types contained in these jars - and the server has a model available for them.
In the case of String for instance, rt.jar is initially UNRESOLVED but after you triggered code completion on "java".<^space> the model gets automatically downloaded and state should be changed to RESOLVED. Can you check your preference page and tell me what't the sate for rt.jar now?
