how to solution this problem [running] java -cp ".:/home/name/.cache/....." main.java Error: Could not find or load main class main Caused by: java.lang.ClassNotFoundException: main

wsdjeg commented 5 years ago

It seems a issue with javaunite.vim, if you can reproduce this issue, please report bug to spacevim.

The checker always shows Error not found Symbol at my classes...

LuisJoseSanchez commented 5 years ago

I can't even execute a simple HelloWorld. This is what I get:

[Running] java -cp ".:/home/luisjose/.cache/vimfiles/repos/github.com/wsdjeg/JavaUnit.vim/bin:" HelloWorld

Error: Could not find or load main class HelloWorld

[Done] exited with code=1 in 0.151742 seconds

wsdjeg commented 5 years ago

you need to save the file. checker layer will compile it.

LuisJoseSanchez commented 5 years ago

Thank you. Now it works. I am used to the "autosave" functionality in Netbeans. It should be a nice improvement for SpaceVim to save the file before compilation if there are changes.

¡Thank you very much for your work! ¡SpaceVim is really cool!

As shown in this page, configuration layer refers to Eclipse files:

[layers.override_cmd]
    java = [
    "java",
    "-Declipse.application=org.eclipse.jdt.ls.core.id1",
    "-Dosgi.bundles.defaultStartLevel=4",
    "-Declipse.product=org.eclipse.jdt.ls.core.product",
    "-Dlog.protocol=true",
    "-Dlog.level=NONE",
    "-noverify",
    "-Xmx1G",
    "-jar",
    "D:\\dev\\jdt-language-server-latest\\plugins\\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar",
    "-configuration",
    "D:\\dev\\jdt-language-server-latest\\config_win",
    "-data",
    "C:\\Users\\Administrator\\.cache\\javalsp"
    ]

So I supose that I need to install Eclipse. I prefer not to install Eclipse in my computer. Is there an alternative configuration? Thank you.

wsdjeg commented 5 years ago

You just need to download the language server, no need to install eclipse, I do not use it.

LuisJoseSanchez commented 5 years ago

Ok. I manage to download "org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar". I also edit the path to make it accessible. But I can't find "config_linux" neither "javalsp".

@LuisJoseSanchez, maybe this could help: https://github.com/prabirshrestha/vim-lsp/wiki/Servers-Java

Where does .cache/javalsp come from? I'm installing on Linux

Worice commented 4 years ago

I am using SpaceVim as Java IDE, just for fun. While configuring ISP, I found that the following windows based step:

[[layers]]
  name = "lsp"
  filetypes = [
    "java"
  ]
  [layers.override_cmd]
    java = [
    "java",
    "-Declipse.application=org.eclipse.jdt.ls.core.id1",
    "-Dosgi.bundles.defaultStartLevel=4",
    "-Declipse.product=org.eclipse.jdt.ls.core.product",
    "-Dlog.protocol=true",
    "-Dlog.level=NONE",
    "-noverify",
    "-Xmx1G",
    "-jar",
    "D:\\dev\\jdt-language-server-latest\\plugins\\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar",
    "-configuration",
    "D:\\dev\\jdt-language-server-latest\\config_win",
    "-data",
    "C:\\Users\\Administrator\\.cache\\javalsp"
    ]

How do I translate it on linux? Aside for the flag config_linux, I clearly cannot find D:\\..., C:\\... equivalency in my system, nor a folder such as jdt-language-server-latest. From Eclipse dedicated page, I am not able to deduce relevant information. Maybe because of my lack of experience. Thanks in advance for any hint, and keep up with the great work!

All I want is to be about to type "sout" + tab to get System.out.println(); I suppose that is what what is mentioned as 'code completion'?

I downloaded the lsp files and place it in the "RTE" folder and set up the spacevim like this:

#Enable Java relevant layers
[[layers]]
  name = "lang#java"

[[layers]]
  name = "lsp"
  filetypes = [
  ┊ "java"
  ]
  [layers.override_cmd]
  ┊ java = [
  ┊ "java",
  ┊ "-Declipse.application=org.eclipse.jdt.ls.core.id1",
  ┊ "-Dosgi.bundles.defaultStartLevel=4",
  ┊ "-Declipse.product=org.eclipse.jdt.ls.core.product",
  ┊ "-Dlog.protocol=true",
  ┊ "-Dlog.level=ALL",
  ┊ "-noverify",
  ┊ "-Xmx1G",
  ┊ "-jar",
  ┊ "~/RTE/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.1200.v20200508-1552.jar",
  ┊ "-configuration",
  ┊ "~/RTE/config_linux",
  ┊ "-data"
  ┊ ]

But after this, I can't enable the lsp in the neovim... When I enter "space + l", nothing showed up.

Thanks a lot if anybody can help me or give me any kind of hints...

why not coc-java?

ENate commented 4 years ago

For Java on Spacevim:

# Java
[[layers]]
  name = "lang#java"

[[layers]]
  name = "lsp"
  filetypes = [
    "java"
  ]
  [layers.override_cmd]
    java = [

"java",
    "-Declipse.application=org.eclipse.jdt.ls.core.id1",
    "-Dosgi.bundles.defaultStartLevel=4",
    "-Declipse.product=org.eclipse.jdt.ls.core.product",
    "-Dlog.protocol=true",
    "-Dlog.level=NONE",
    "-noverify",
    "-Xmx1G",

"-jar",
    "~/lsp/newlsp/repository/plugins/org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar"
        "-configuration",
        "~/lsp/newlsp/repository/config_linux"
        "-data",
        "~/.cache/javalsp"

]

It is important that you get org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar and ~/lsp/newlsp/repository/config_linux right (Note that versions may differ for the former). Usually both the config_linux and org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar are often available in same main folder (seeing from your snippet)! I used the ones from the latest version of eclipse Java EE. It seems you can get these files from an eclipse.org site or similar. It was a hassle to get it working at first, but when you do, you may never want to use any other IDE (because you get back your CPU/GPU) and enjoy the benefits of Spacevim as a Java IDE. Hope this helps. Note: Make sure you installed the proper version of pyvim (Use the healthcheck command to see your configs on Spacevim/neovim. Check your neovim (Spacevim for neovim) compatibility with Python2 or Python3. Conflicts can occur and cause a bit of headache. I had to uninstall Spacevim, neovim, vim a few times before deciding to configure everything to work using Python 3.6+ only.
