javacomplete2 cannot work without sudo privileges? #71

Closed SPiCaRiA closed 8 years ago

SPiCaRiA commented 8 years ago

I installed javacomplete2 as well as YouCompleteMe, but my javacomplete2 doesn't work unless i open gVim with sudo privileges:

$ sudo gvim

my .vimrc autocmd FileType java set omnifunc=javacomplete#Complete

not problem with YCM, ive tried disabling YCM but still need sudo privileges...

why would this happen? im a new vimer, many thx!!

wsdjeg commented 8 years ago

please use vundle -or neobundle install JC2;

SPiCaRiA commented 8 years ago

i used vim-plug to install JC2, isn't that available?

wsdjeg commented 8 years ago

do you add this to ~/.vimrc or ~/.gvimrc

SPiCaRiA commented 8 years ago

what do u mean "this"? Plug 'artur-shaik/vim-javacomplete2' simply add this and the previous one

wsdjeg commented 8 years ago

please use these command

mv ~/.vimrc ~/.vimrc.backup
mv ~/.vim ~/.vimback
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

copy this to ~/.vimrc

set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'
Plugin 'artur-shaik/vim-javacomplete2'
call vundle#end()
filetype plugin indent on
SPiCaRiA commented 8 years ago
  1. still doesn't work :(
  2. ive found that java kg.ash.javavi.Javavi has taken most of CPU when auto completing, even sometimes reach 100+%, do u have any method of improvement?

sorry for bothering ;D

wsdjeg commented 8 years ago

you can look at my vimrc

https://github.com/wsdjeg/DotFiles/blob/master/vimrc_neobundle

SPiCaRiA commented 8 years ago

thanks a lot, but i think it's not the problem with .vimrc, because we ve already tried with an empty .vimrc just now.

i'm wandering if JC2 needs permission to do with files that outside /home?

artur-shaik commented 8 years ago

@rundisR, no, you don't need super user privileges. Not sure what can be a problem.

SPiCaRiA commented 8 years ago

however i remember it says that JC2 need to write file to /lib?

wsdjeg commented 8 years ago

vim-javacomplete2/lib

SPiCaRiA commented 8 years ago

oh sorry... i thought it would be /lib

SPiCaRiA commented 8 years ago

it's weird that i found that my JC2 partly work without sudo, but not all function!

it seems that only method completion is available without sudo Comparison: it says -- Omni completion (^O^N^P) Pattern not found for the non-sudo one (sorry im using the chinese version;D)

wsdjeg commented 8 years ago

你玩ubuntu 不用vim 用GVIM 我也是醉了

you are using ubuntu,why do not use vim instead of gvim

SPiCaRiA commented 8 years ago

有gvim用为何不用。。。我又不需要编辑服务器的文件，只是想要一个顺手的编辑器而已。。。

p.s.: 我觉得在github上还是用英文比较礼貌些？毕竟有外国人看不懂

wsdjeg commented 8 years ago

sorry maybe you can try use vim whit the same vimrc

SPiCaRiA commented 8 years ago

what do u mean "the same vimrc"? i suppose that it can't be the problem with vimrc since we've tried a fresh vimrc

wsdjeg commented 8 years ago

can you chow me the result of gvim and sudo gvim :echo echo $MYVIMRC

SPiCaRiA commented 8 years ago

both shows /home/rundis/.vimrc for :echo $MYVIMRC

wsdjeg commented 8 years ago

the comfig file of gvim is not ~/.gvimrc ?

wsdjeg commented 8 years ago

javac -version java -version

SPiCaRiA commented 8 years ago
  1. i used to use .gvimrc as my config file, soon i found it annoying to use separate file so i simply use one file
  2. Result: i installed oracle jdk instead of openjdk i think thats not problem with jdk or it won't work even with sudo
rundis@TreeDiagram:~$ java -version

wsdjeg commented 8 years ago

i am using openjdk oracle jdk will broken the dist-upgrade of ubuntu! i think you can try to do these things!

rm -rf ~/.vim/bundle/vim-javacomplete2 
cd 
vim test
"then the vundle will install the uninstall plugin vim-javacomplete2
:w close the vim 
re open vim by vim test
"the vim-javacomplete2 will autocompile on the first time
re open vim by vim Hello.java
then try with c-x c-o
SPiCaRiA commented 8 years ago

oh i see, there're some problem will compiling JC2: 

"Hello.java" 0L, 0C
:!javac -d /home/rundis/.vim/bundle/vim-javacomplete2/libs/javavi/target/classes

注: 某些输入文件使用了未经检查或不安全的操作。 注: 有关详细信息, 请使用 -Xlint:unchecked 重新编译。 it is just a warning

SPiCaRiA commented 8 years ago

so do i have to recompile as it says with -Xlint:unchecked?

artur-shaik commented 8 years ago

No, you don't need to recompile. It's ok for now.

artur-shaik commented 8 years ago

Can you try to turn on logging, and put content here?

  1. JCdebugEnableLogs
  2. run completions
  3. JCdebugGetLogContent
artur-shaik commented 8 years ago

And run this command in console: java -XshowSettings

artur-shaik commented 8 years ago

Can you check this directory /home/rundis/.java/jdk1.8.0_51/jre, can you read it.

And also can you check your env variable JAVA_HOME, have you set it, and if yes, what is there?

wsdjeg commented 8 years ago

I think i know where is the problem! please don't install JDK manually use this command

sudo add-apt-repository ppa:webupd8team/java  
sudo apt-get update  
sudo apt-get install oracle-java8-installer

or

sudo apt-get install openjdk-8-jdk

and delete the JAVA_HOME in your ~/.profile or~/.bashrc

SPiCaRiA commented 8 years ago

@artur-shaik

  1. i can access to jre
  2. $JAVA_HOME shows /home/rundis/.java/jdk1.8.0_51 which exactly my jdk locate

@wsdjeg why not manually install JDK? actually i used jenv to install my jdk

artur-shaik commented 8 years ago

By the way, can you check, is java process exist, after you run completion?

SPiCaRiA commented 8 years ago

@artur-shaik yes, i get java kg.ash.javavi.Javavi after completion

artur-shaik commented 8 years ago

Ok. Also, can you try run completion after dot in imports. import java.| Doesn't it work, too?

SPiCaRiA commented 8 years ago

@artur-shaik

these are the situation ive tested: DOESN'T WORK(needs sudo): import java| import java.| List list = new Li| they all shows -- Omni completion (^O^N^P) Pattern not found

WORK: list.|

artur-shaik commented 8 years ago

What java uses your root user? The same, or it some another? It's really weird issue.

wsdjeg commented 8 years ago

i think it is a problem of how does he install the JDK!

wsdjeg commented 8 years ago

@rundisR can you try this commands

cd ~/.vim/bundle/vim-javacomplete2
mv -rf libs/javavi/target
cd libs/javavi/
mvn compile
SPiCaRiA commented 8 years ago

@wsdjeg i reinstalled jdk with

sudo add-apt-repository ppa:webupd8team/java  
sudo apt-get update  
sudo apt-get install oracle-java8-installer

but nothing changed i will try this new one

@artur-shaik i'm not sure what u mean, but i only have two user: root and rundis(no sudo privileges)

wsdjeg commented 8 years ago

@artur-shaik

Can you check this directory /home/rundis/.java/jdk1.8.0_51/jre, can you read it. And also can you check your env variable JAVA_HOME, have you set it, and if yes, what is there? translate 检测这个文件夹你是否可读 检测JAVA_HOME环境变量是否设置，如果设置了，指向哪里？

artur-shaik commented 8 years ago

I mean, can you login under root, and run java -XshowSettings, and check your JAVA_HOME, under root.

SPiCaRiA commented 8 years ago

sorry for misunderstanding... something wrong on my ubuntu, ill try to reinstall it this afternoon and try it tomorrow

wsdjeg commented 8 years ago

SPiCaRiA commented 8 years ago

wsdjeg commented 8 years ago

SPiCaRiA commented 8 years ago

@wsdjeg you are right, its the problem with my jdk

appreciate for your help!! @wsdjeg @artur-shaik
