javalsp *ale-java-javalsp*
|
|
|
|
To enable Java LSP linter you need to download and build the vscode-javac
|
|
language server from https://github.com/georgewfraser/java-language-server.
|
|
|
|
Before building the language server you need to install pre-requisites: npm,
|
|
maven, and protobuf. You also need to have Java 13 and JAVA_HOME properly
|
|
set.
|
|
|
|
After downloading the source code and installing all pre-requisites you can
|
|
build the language server with the included build.sh script:
|
|
|
|
scripts/build.sh
|
|
|
|
This will create launch scripts for Linux, Mac, and Windows in the dist folder
|
|
within the repo:
|
|
|
|
- lang_server_linux.sh
|
|
- lang_server_mac.sh
|
|
- lang_server_windows.sh
|
|
|
|
To let ALE use this language server you need to set the
|
|
g:ale_java_javalsp_executable variable to the absolute path of the launcher
|
|
executable for your platform.
|
|
|
|
g:ale_java_javalsp_executable *g:ale_java_javalsp_executable*
|
|
*b:ale_java_javalsp_executable*
|
|
Type: |String|
|
|
Default: `''`
|
|
|
|
This variable must be set to the absolute path of the language server launcher
|
|
executable. For example:
|
|
>
|
|
let g:ale_java_javalsp_executable=/java-language-server/dist/lang_server_linux.sh
|
|
<
|
|
|
|
g:ale_java_javalsp_config *g:ale_java_javalsp_config*
|
|
*b:ale_java_javalsp_config*
|
|
Type: |Dictionary|
|
|
Default: `{}`
|
|
|
|
The javalsp linter automatically detects external depenencies for Maven and
|
|
Gradle projects. In case the javalsp fails to detect some of them, you can
|
|
specify them setting a dictionary to |g:ale_java_javalsp_config| variable.
|
|
>
|
|
let g:ale_java_javalsp_config =
|
|
\ {
|
|
\ 'java': {
|
|
\ 'externalDependencies': [
|
|
\ 'junit:junit:jar:4.12:test', " Maven format
|
|
\ 'junit:junit:4.1' " Gradle format
|
|
\ ],
|
|
\ 'classPath': [
|
|
\ 'lib/some-dependency.jar',
|
|
\ '/android-sdk/platforms/android-28.jar'
|
|
\ ]
|
|
\ }
|
|
\ }
|
|
|
|
The Java language server will look for the dependencies you specify in
|
|
`externalDependencies` array in your Maven and Gradle caches ~/.m2 and
|
|
~/.gradle.
|
|
|
|
===============================================================================
|
|
eclipselsp *ale-java-eclipselsp*
|
|
|
|
To enable Eclipse JDT LSP linter you need to clone and build the eclipse.jdt.ls
|
|
language server from https://github.com/eclipse/eclipse.jdt.ls. Simply
|
|
clone the source code repo and then build the plugin:
|
|
|
|
./mvnw clean verify
|
|
|
|
Note: currently, the build can only run when launched with JDK 11. More
|
|
recent versions can be used to run the server though.
|
|
|
|
After build completes the files required to run the language server will be
|
|
located inside the repository folder `eclipse.jdt.ls`. Please ensure to set
|
|
|g:ale_java_eclipselsp_path| to the absolute path of that folder.
|
|
|
|
You could customize compiler options and code assists of the server.
|
|
Under your project folder, modify the file `.settings/org.eclipse.jdt.core.prefs`
|
|
with options presented at
|
|
https://help.eclipse.org/neon/topic/org.eclipse.jdt.doc.isv/reference/api/org/eclipse/jdt/core/JavaCore.html.
|
|
|
|
g:ale_java_eclipselsp_path *g:ale_java_eclipselsp_path*
|
|
*b:ale_java_eclipselsp_path*
|
|
|
|
Type: |String|
|
|
Default: `'$HOME/eclipse.jdt.ls'`
|
|
|
|
Absolute path to the location of the eclipse.jdt.ls repository folder. Or if
|
|
you have VSCode extension installed the absolute path to the VSCode extensions
|
|
folder (e.g. $HOME/.vscode/extensions/redhat.java-0.4x.0 in Linux).
|
|
|
|
|
|
g:ale_java_eclipselsp_executable *g:ale_java_eclipse_executable*
|
|
*b:ale_java_eclipse_executable*
|
|
Type: |String|
|
|
Default: `'java'`
|
|
|
|
This variable can be set to change the executable path used for java.
|
|
|
|
|
|
g:ale_java_eclipselsp_config_path *g:ale_java_eclipse_config_path*
|
|
*b:ale_java_eclipse_config_path*
|
|
Type: |String|
|
|
Default: `''`
|
|
|
|
Set this variable to change the configuration directory path used by
|
|
eclipselsp (e.g. `$HOME/.jdtls` in Linux).
|
|
By default ALE will attempt to use the configuration within the installation
|
|
directory.
|
|
This setting is particularly useful when eclipselsp is installed in a
|
|
non-writable directory like `/usr/share/java/jdtls`, as is the case when
|
|
installed via system package.
|
|
|
|
|
|
g:ale_java_eclipselsp_workspace_path *g:ale_java_eclipselsp_workspace_path*
|
|
*b:ale_java_eclipselsp_workspace_path*
|
|
|
|
Type: |String|
|
|
Default: `''`
|
|
|
|
If you have Eclipse installed is good idea to set this variable to the
|
|
absolute path of the Eclipse workspace. If not set this value will be set to
|
|
the parent folder of the project root.
|
|
|
|
g:ale_java_eclipselsp_javaagent *g:ale_java_eclipselsp_javaagent*
|
|
*b:ale_java_eclipselsp_javaagent*
|
|
|
|
Type: |String|
|
|
Default: `''`
|
|
|
|
A variable to add java agent for annotation processing such as Lombok.
|
|
If you have multiple java agent files, use space to separate them. For example:
|
|
>
|
|
let g:ale_java_eclipselsp_javaagent='/eclipse/lombok.jar /eclipse/jacoco.jar'
