When open vim get en error?

[crazy-canux]

Actual behavior (Required!)

Download and install javacomplate2.

Expected behavior (Required!)

use vim to edit *.java files.

The steps to reproduce actual behavior (Required!)

1. ... Download and install this plugin in ~/.vim/bundle/
2. ...Add "autocmd Filetype java setlocal omnifunc=javacomplete#Complete" in ~/.vimrc
3. ...Trying to edit a file like test.java. But got an error:

shell returned 2 No Javavi library classes found, it means that we couldn't compile it. Do you have JDK8+ installed?

But, I already installed openjdk8. And java -version can prove it.

Environment (Required!)

• OS: Ubuntu14.04
• Vim version: 7.4
• Neovim version: pathogen

  Q&A

• Yes, I tried minimal .vimrc configuraion.
• Yes, I have enabled logs with JCdebugEnableLogs and can put here content of JCdebugGetLogContent command, if you need.
• Even, if you wish, I can set g:JavaComplete_JavaviDebug to 1, than set g:JavaComplete_JavaviLogfileDirectory, and put here server logs, too.

  Screenshot (Optional)

  The output of :redir and :message (Optional)

@crazy-canux can you try :echo javacomplete#server#GetCompiler()

and also try to use :call javacomplete#server#Compile()

[crazy-canux]

Sure,

And got this errors:

javac: directory not found: /home/chengca/.vim/bundle/vim-javacomplete2-master/libs/javavi/target/classes

[wsdjeg]

But, I already installed openjdk8. And java -version can prove i

javac: directory not found: /home/chengca/.vim/bundle/vim-javacomplete2-master/libs/javavi/target/classes

please do not use vim-javacomplete2-master ,change it to vim-javacomplete2

[wsdjeg]

if you just down load the zip file ,please unzip it

[crazy-canux]

I have lots of plugins in ~/.vim/bundle, and others are working well. Of course I unzip it. mv vim-javacomplete2-master vim-javacomplete2 Still the same error.

[wsdjeg]

can you try with call mkdir('/home/chengca/.vim/bundle/vim-javacomplete2-master/libs/javavi/'. join(['target', 'classes'], g:FILE_SEP), "p")

BTW, are you using pathogen?

[crazy-canux]

Yes, I am using pathogen.

How to try with " call mkdir('/home/chengca/.vim/bundle/vim-javacomplete2-master/libs/javavi/'. join(['target', 'classes'], g:FILE_SEP), "p")" ?

[wsdjeg]

run in vim .

call mkdir('/home/chengca/.vim/bundle/vim-javacomplete2-master/libs/javavi/'. join(['target', 'classes'], g:FILE_SEP), "p")

[crazy-canux]

E739: Cannot create directory: /home/chengca/.vim/bundle/vim-javacomplete2-master E739: Cannot create directory: /home/chengca/.vim/bundle/vim-javacomplete2-master/libs/javavi/target/classes

[wsdjeg]

it is due to the different file permission; and you can run this command in terminal ,and see the different file permission between them.

ls -l /home/chengca/.vim/bundle

[wsdjeg]

Recommend to use dein.vim to manager your plugins instead of download plugin yourself.

[wsdjeg]

                            *mkdir()* *E739*
mkdir({name} [, {path} [, {prot}]])
        Create directory {name}.
        If {path} is "p" then intermediate directories are created as
        necessary.  Otherwise it must be "".
        If {prot} is given it is used to set the protection bits of
        the new directory.  The default is 0755 (rwxr-xr-x: r/w for
        the user readable for others).  Use 0700 to make it unreadable
        for others.  This is only used for the last part of {name}.
        Thus if you create /tmp/foo/bar then /tmp/foo will be created
        with 0755.
        Example: >
            :call mkdir($HOME . "/tmp/foo/bar", "p", 0700)
<       This function is not available in the |sandbox|.
        Not available on all systems.  To check use: >
            :if exists("*mkdir")
<

No, I didn't see any different.

[artur-shaik]

Why root? Not all plugins need write permissions to it directory. JC2 plugin just cannot compile server lib to generate completions, because of your permissions.

[crazy-canux]

Oh my god! Yes, you are right. root didn't work.

@artur-shaik @wsdjeg thanks very much!!!
