I also created a issue in Shougo/deoplete.nvim #1133

artur-shaik commented 3 years ago

Please, can you pack minimal gradle powered project for me, so I can start debug straight away.

NobodyXu commented 3 years ago

Well, it's actually very easy to create a simple project using gradle.

First, make sure that you are using gradle 6.6.1, that is the gradle that causes the bug for me. Then run gradle init, select '2'(application), '3' (Java), '1' (Groovy), 1 (JUnit 4) and give it any project name.

If everything goes well, you then already has a minimal gradle powered project.

NobodyXu commented 3 years ago

I have a project created via gradle init, and under src/main/java/project_name/submodule, there's a submodule.

When I imported a class from the parent module, I sometimes experience unknown error from vim-javacomplete2 when it is auto completeing my input.

artur-shaik commented 3 years ago

can you try this branch: hotfix/issue-443, and paste here shown errors?

NobodyXu commented 3 years ago

Sure

I will give you feedback once I get any error.

I just got the error again when I am typing, and mistakenly press space to continue typing xD

@NobodyXu hm, actually, there is nothing usefull, I thought it should print much more information on error. I've merged that branch to master, so you can switch to latest version.

NobodyXu commented 3 years ago

Thx.

If the errors occur again, I will try to get a more complete log next time.

Or is there any nvim/deoplete function that can show log that I wasn't aware of?

Ok, lets try one more time on this branch: hotfix/issue-443

NobodyXu commented 3 years ago

OK

NobodyXu commented 3 years ago

After I got on that branch, I found out that all dependencies I specified in build.gradle cannot be found by vim-javacomplete2.

All my imports to these modules gives me error.

NobodyXu commented 3 years ago

I tried to reinstall the plugin from the bran hotfix, but only got more error:

And import still doesn't work in gradle project.

NobodyXu commented 3 years ago

I just verified that the "unable to import" part isn't caused by this package.

It's more likely there is something wrong with the specific git branch I was working on.

Sorry for the false alarm.

NobodyXu commented 3 years ago

BTW, I also received strange error message when I tried to save my file:

"Sqlite3Test.java" 215L, 7830C written
could not open socket, try again
could not open socket, try again
could not open socket, try again

Not sure whether this is caused by vim-javacomplete2.

NobodyXu commented 3 years ago

Just confirmed this is a vim-javacomplete2 problem.

After I removed it, nothing goes wrong.

artur-shaik commented 3 years ago

Can you try to clear jc2 cache by doing: rm ~/.cache/javacomplete2/ ?

NobodyXu commented 3 years ago

I tried, but still got the could not open socket, try again error when saving the file.

Seems like a different kind of error.

artur-shaik commented 3 years ago

Yeah, you are right, something new, after what action it happened?

NobodyXu commented 3 years ago

It happened when I was changing the following code:

import javafx.util.Pair;

for (Pair<Path, String> pair: new Pair<Path, String>[](                                           
   Path.A, "A",
   Path.B, "B",
    Path.C, "C",
    Path.D, "D",
    Path.E, "E",
    Path.F, "F"})
{

To:

import javafx.util.Pair;
import java.util.Arrays;

for (Pair<Path, String> pair: Arrays.asList(
    new Pair<Path, String>(Path.A, "A"),
    new Pair<Path, String>(Path.B, "B"),
    new Pair<Path, String>(Path.C, "C"),
    new Pair<Path, String>(Path.D, "D"),
    new Pair<Path, String>(Path.E, "E"),
    new Pair<Path, String>(Path.F, "F")))
{

I recalled that I have already added new Pair<Path, String>( when it happened.

NOTE that Path is an enum.

artur-shaik commented 3 years ago

Pushed some changes, looks like the bug.

NobodyXu commented 3 years ago

Since last update, I haven't yet experienced one error.

artur-shaik commented 3 years ago

Ok, let's merge it, and if any will thrown again, please reopen this issue. And thanks for participation.
