Missing argument for option: n

[emmanueltouzery]

I am getting this error right now:

Missing argument for option: n

Eclipse:

Version: Mars.1 (4.5.1)
Build id: Z20151013-1620

Java:

openjdk version "1.8.0_65"
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)

the eclimd server prints this at the time of the error:

NGSession 1: 127.0.0.1: org.eclim.command.Main exited with status 1

That said it's my first attempt at setting up eclim, it's very likely I misconfigured something. Using it through the spacemacs integration.

Getting this on find-references but it seems most of the commands trigger that problem.

Seems to be like #180 which was closed.

Can you turn on debug messages and paste what gets added to the *Messages* buffer?

To turn on debug messages use M-: (setq eclim-print-debug-messages t). Then call M-x eclim-java-find-declaration. After this you should see a line like the following added to the *Messages* buffer.

Executing: /home/user/bin/eclim -command java_search -n my_project -f src/main/java/org/company/project/MyClass.java -o 1151 -l 3 -x declaration

hmm I ran it several times, I think I got the important error only the first time. It's got to be "invalid project":

I'm probably guilty of not having RTFM here... I just setup the environment, opened a java file and then expected find-references to work. I think I must set up an eclim project probably.. I'll try to read the documentation. Still, even if that's the reason, I guess the error message could be improved.

[emmanueltouzery]

yes, setting up things using

mvn eclipse:eclipse -DdownloadSources -DdownloadJavadocs

and

M-x eclim-project-create

makes it work! So maybe a more newbie-friendly error message would be better, but otherwise it's not "really" a bug.

I'm using Gradle on my project. If I'm running eclim and I do gradle cleanEclipse in a shell at my project root, then after saving a .java file from my project in Emacs, eclimd throws org.eclipse.core.internal.resources.ResourceException stating the the .project file is missing.

Maybe eclim should check that this file is present before issuing commands to eclimd?

Should this be reported as a separate bug?
