completion hangs on scala.tuple2

[richox]

code:

package com.xiaoju.sparksql;

import scala.Tuple2;

public class Main {
    public static void main(String[] args) {
        Tuple2<String, Long> tuple;
        tuple.

[richox]

tested on two different machine, always happen.

[richox]

package com.xiaoju.sparksql;

import scala.Tuple3;

public class Main {
    public static void main(String[] args) {
        Tuple3<String, Long, Long> tuple;
        tuple.
    }   
}

completion for tuple3 is OK, strange.

[richox]

completion for Tuple4 not works (no popup menu at all) but won't hang. strange too.

[wsdjeg]

@richox is it same as https://github.com/artur-shaik/vim-javacomplete2/issues/180 ?

[richox]

@wsdjeg i don't think they are the same problem. this issue happens without generic.

Tuple2 a;
a.

will also hang.

[wsdjeg]

where is Tuple2 comes from ,I can not import this class.

[richox]

@wsdjeg Tuple2 comes from scala-library-2.10.2.jar

[wsdjeg]

I know ,but I can not complete after import scala.

EDIT: mvn compile success

[wsdjeg]

I still can not complete the import statement, no result after import scala.

[artur-shaik]

@wsdjeg , check if you have jars in ~/.m2/repository/org/scala-lang

I had the same problem, those directories were empty. I removed them, made mvn verify, and clean jc2 cache.

[wsdjeg]

I think I have download the necessary jars

[richox]

I think the problem is not fully fixed, now completion for Tuple2 works, but Tuple3, Tuple4, ... still hang. completion for SparkConf also hang: http://pan.baidu.com/s/1dDZk3sP

[artur-shaik]

Strange, but I have it worked. All tuples and SparkConf give me completions. May be you need clear jc2 cache in ~/.cache/javacomplete2/ ?

[wsdjeg]

here is my pom.xml

and here is my App.java

package com.wsdjeg.javalibs;
import scala.Tuple3;
/**

public class App
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
        Tuple3 s;
    }
}

I can use mvn clean compile ,but I can not complete after import scala. also java check show no error

[artur-shaik]

@wsdjeg, can you look, if you have path to scala lib in classpath cache?

[wsdjeg]

I think g:JavaComplete_LibsPath contains all the needed jars,because my plugin JavaUnit.vim works well ,and it use g:JavaComplete_LibsPath as classpath.

[artur-shaik]

@wsdjeg but can you just check, what scala libraries you have in ~/.cache/javacomplete2/classpath/cachefile?

[richox]

@artur-shaik I cleared the cache and still have the problem.

it's strange that the problem happens only on some specified class, for example completion works for SparkContext but hangs for SparkConf

[artur-shaik]

@richox by the way, there was some changes in java lib, have you recompiled it?

[richox]

@artur-shaik I remove the plugin and cache, then reinstall it from scratch, now: completion for SparkConf works completion for Tuple2 works completion for Tuple3 works completion for Tuple2<Object, Object> works completion for Tuple3<Object, Object, Object> Pattern not found

[wsdjeg]

@richox can you complete after import scala._

[richox]

@wsdjeg yes i can

[richox]

@artur-shaik it was my fault, completion for Tuple3<Object, Object, Object> does not hang but reports "Pattern not found"

[artur-shaik]

Ok, some more fixes. Please, recompile javavi, before test.

[wsdjeg]

still can not complete after import scala.; I hava update jc2 and recompile ,alse delete the ~/.cache/javacomplete2, restart vim my ~/.cache/javacomplete2/ contains this files and the pom_xml is

[wsdjeg]

I found there is no scala-library

[artur-shaik]

@wsdjeg, yeah, and those Tuples live in scala-library. I don't know why maven doesn't download this library sometimes. I had the same issue, then I cleared maven repository's directory org/scala/ and builded project. After that maven downloaded all libs.

[wsdjeg]

ok I try it again,but can you show me your test pom.xml?

[richox]

@artur-shaik now completion for Tuple3<Object, Object, Object> works! thanks veryMuch

[wsdjeg]

still can not work,still has no scala-library in g:JavaComplete_libpath

[artur-shaik]

17 directories, 32 files

[wsdjeg]

just same as mine,really do not know why I can not complete after that

[wsdjeg]

can you show me the ~/.cache/javacomplete2/classpath/path to your pom_xml,I will compare your with mine

[artur-shaik]

@wsdjeg, can you run this command:

mvn --file pom.xml help:effective-pom dependency:build-classpath -DincludeScope=test

and look for dependencies classpath.

[wsdjeg]

this contains scala-library but the ~/.cache/javacomplete2/classpath/path to your pom_xml has no ,I do not know why.

[wsdjeg]

you can see my last commens for the pom_xml

hdfs/2.2.0/hadoop-hdfs-2.2.0.jar:/home/wsdjeg/.m2/repository/org/codehaus/jackson/jackson-mapper-asl/1.9.13/jackson-mapper-asl-1.9.13.jar:/home/wsdjeg/.m2/repository/org/apache/hadoop/hadoop-yarn-api/2.2.0/hadoop-yarn-:/home/wsdjeg/sources/JavaLibs/target/classes:/home/wsdjeg/sources/JavaLibs/target/test-classes

the file miss the jars after yarn-api/2.2.0/hadoop-yarn-

[wsdjeg]

Ok I got it,it is the issue of neovim not this plugin,now vim works well,but neovim miss many jars and I will report it to neovim group

[artur-shaik]

Hm, what is the reason of this issue?

[wsdjeg]

because the neovim missed the stdout date of mvn classpath,and do not write it into cache file. missed after yarn-api/2.2.0/hadoop-yarn-

[richox]

@artur-shaik another problem, after applying the newest fixes, completion for Map.Entry<Object, Object> broken (reports "Pattern not found")

[wsdjeg]

you see it only has 8346 chars when i use vim create the cache it has 12488 chars

[artur-shaik]

@wsdjeg ok, now I see. @richox, looks like this one is old issue. It doesn't work for me even if I rollback.

[artur-shaik]

@richox will open another issue.

[wsdjeg]

@artur-shaik I have fix this issue for neovim,should I open the PR,but I think it is not the best selution.
