===============================================================================
ALE Java Integration *ale-java-options*
===============================================================================
checkstyle *ale-java-checkstyle*

*b:ale_java_checkstyle_config*
Type: |String|
Default: `'/google_checks.xml'`
A path to a checkstyle configuration file.
If a configuration file is specified with |g:ale_java_checkstyle_options|,
it will be preferred over this setting.
The path to the configuration file can be an absolute path or a relative
path. ALE will search for the relative path in parent directories.
g:ale_java_checkstyle_executable *g:ale_java_checkstyle_executable*
*b:ale_java_checkstyle_executable*
Type: |String|
Default: 'checkstyle'
This variable can be changed to modify the executable used for checkstyle.

*b:ale_java_checkstyle_options*
Type: |String|
Default: `''`
This variable can be changed to modify flags given to checkstyle.
If a configuration file is specified with `-c`, it will be used instead of
configuration files set with |g:ale_java_checkstyle_config|.

g:ale_java_javac_classpath *g:ale_java_javac_classpath*
*b:ale_java_javac_classpath*

g:ale_java_javac_sourcepath *g:ale_java_javac_sourcepath*
*b:ale_java_javac_sourcepath*
Type: |String| or |List|

This variable can set multiple source code paths, the source code path is a
relative path (relative to the project root directory).
Example:
String type:
Note that the unix system separator is a colon(`:`) window system
is a semicolon(`;`).
>
let g:ale_java_javac_sourcepath = 'build/gen/source/xx/main:build/gen/source'
<
List type:
>
let g:ale_java_javac_sourcepath = [
\ 'build/generated/source/querydsl/main',
\ 'target/generated-sources/source/querydsl/main'
\ ]
<
===============================================================================
google-java-format *ale-java-google-java-format*
g:ale_java_google_java_format_executable
*g:ale_java_google_java_format_executable*
*b:ale_java_google_java_format_executable*
Type: |String|
Default: `'google-java-format'`
See |ale-integrations-local-executables|
g:ale_java_google_java_format_options *g:ale_java_google_java_format_options*
*b:ale_java_google_java_format_options*
Type: |String|
Default: `''`
This variable can be set to pass additional options
===============================================================================
pmd *ale-java-pmd*
g:ale_java_pmd_options *g:ale_java_pmd_options*
*b:ale_java_pmd_options*
Type: String
Default: '-R category/java/bestpractices'
This variable can be changed to modify flags given to PMD. Do not specify -f
and -d. They are added automatically.
===============================================================================
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.
Simply download the source code and then build a distribution:
scripts/link_mac.sh
or
scripts/link_windows.sh
This generates a dist/mac or dist/windows directory that contains the
language server. 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 in this directory.
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/mac/bin/launcher
<
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_executable =
\ {
\ '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 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 8. JDK 9 or 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'
<
