=============================================================================== ALE Java Integration *ale-java-options* =============================================================================== checkstyle *ale-java-checkstyle* g:ale_java_checkstyle_config *g:ale_java_checkstyle_config* *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. g:ale_java_checkstyle_options *g:ale_java_checkstyle_options* *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|. =============================================================================== javac *ale-java-javac* g:ale_java_javac_classpath *g:ale_java_javac_classpath* *b:ale_java_javac_classpath* Type: |String| Default: `''` This variable can be set to change the global classpath for Java. g:ale_java_javac_executable *g:ale_java_javac_executable* *b:ale_java_javac_executable* Type: |String| Default: `'javac'` This variable can be set to change the executable path used for javac. g:ale_java_javac_options *g:ale_java_javac_options* *b:ale_java_javac_options* Type: |String| Default: `''` This variable can be set to pass additional options to javac. =============================================================================== 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. =============================================================================== uncrustify *ale-java-uncrustify* See |ale-c-uncrustify| for information about the available options. =============================================================================== vim:tw=78:ts=2:sts=2:sw=2:ft=help:norl:
