Java find references don't find references

[kleewho]

When calling eclim-java-find-references I get buffer with this content:

-*- mode: eclim-find; default-directory: /home/corpo-user/Dokumenty/Projekty/Acme/foo/foo-domain/src/main/java/com/acme/domain -*-

eclim java_search -p ChannelView

and as you can see zero results. Making the same call from command-line:

./eclim -command java_search -p ChannelView 
[{"filename":"/home/corpo-user/Dokumenty/Projekty/Acme/foo/foo-domain/src/main/java/com/acme/domain/ChannelView.java","offset":304,"length":11,"line":12,"column":14,"message":"com.acme.domain.ChannelView"}]

Obviously the call is wrong cause even looking at the function definition I see that the call itself should at least have -x references somewhere. Calling it from cli like this:

./eclim -command java_search -p ChannelView -t all -x references

returns plenty of results

It seems that content of eclim find buffer don't have anything to do with what was actually sent. Content is always the same https://github.com/senny/emacs-eclim/blob/master/eclim.el#L379

It's working for me when I have point on any text.

Lucky guy! If the situation occur then I will try to reproduce it in my test project. I have prepared test project but I'm looking for when it's failing. If possible do not close this issue yet as I'm sure that it's failing

[kleewho]

I found the problem... consider this project:

parent
 |- lib
 |- proj

lib is a dependency of proj and both of them are submodules of parent. Looking for anything in lib is failing probably because eclim returns wrong project for files present in lib. Command:

~/opt/eclipse/eclim -command project_by_resource -f /home/user/parent/lib/src/main/java/com/acme/Library.java

instead returning lib returns parent and then eclim can't find any references. Calling java_search with fixed project name returns correct list of references but call with wrongly set project name returns empty list.

I will clean workspace and reimport project. Also I will search for similar issue in eclim issues

[kleewho]

Reimport did the trick. Closing cause it doesn't sound like an emacs-eclim issue

You're a fireball of activity! 🔥

I've experienced the same issue, it starts since my last updates of packages.
Now eclim-java-find-declaration giving me nothing. Reimport does not work for me.
Here is the content of eclim-find buffer:

-*- mode: eclim-find; default-directory: /home/joey/workspace/icon/libicon/src/main/java/com/philips/prna/util/ -*-

eclim java_search -p TermMap

I have icon as the parent project, and libicon is one of the sub-project.

I've been experiencing some similar problems from time to time but I can't seem to find any pattern. @liujoey can you describe how exactly your project looks like? How do you import it? I've got concerns about multimodule maven project with parent being simple pom that groups couple projects. Do you have similar setup? I'm willing to try to tackle this once again, but I'm looking for some inspiration

It was working last week. Then I did Emacs package update earlier this week, don't remember what's the version I was using previously.

I don't think it's anything wrong with Eclim. I've no problem to jump to declaration when using Vim eclim plugin. And from the command line, the eclim command result looks also good.

$ /opt/eclipse_luna/eclim -command java_search -p TermMap
[{"filename":"/home/joey/workspace/icon/libicon/src/main/java/com/philips/prna/util/TermMap.java","offset":328,"length":7,"line":17,"column":14,"message":"com.philips.prna.util.TermMap"}]

It's just that the updated emacs-eclim can't jump to the file, I guess.

[liujoey]

I tested eclim-java-find-type, and it works
Now I was confused. The code of eclim-java-find-declaration uses -n -f -o options for java_search.

(defun eclim-java-find-declaration ()
  "Find and display the declaration of the java identifier at point."
  (interactive)
  (let ((i (eclim--java-identifier-at-point t)))
    (eclim/with-results hits ("java_search" "-n" "-f" ("-o" (car i)) ("-l" (length (cdr i))) ("-x" "declaration"))
      (eclim--find-display-results (cdr i) hits t))))

When I run command:

/opt/eclipse_luna/eclim -command java_search -n -f -o TermMap -l 7 -x declaration

I got Missing argument for option: n

according to the eclim document, there's no -n or -f options, it only supports -p, am I missing something here?

[kleewho]

I think eclim documentation might be outdated. Look here. https://github.com/ervandew/eclim/blob/master/org.eclim.jdt/java/org/eclim/plugin/jdt/command/search/SearchCommand.java#L79-L92
