This is vim-javacomplete2, an omni-completion plugin for Java requiring vim 7.
It includes javacomplete.vim, java_parser.vim, javavi (reflecton and source parsing library), javavibridge.py, and the javaparser library.
I have kept java_parser.vim for local (live) continuous parsing, because the javaparser library can't parse unfinished files.
For now the main difference from the original plugin is the existence of a server-like java library, that allows communication over sockets. This speeds up reflection and parsing.
One more issue I had with the original javacomplete plugin is losing my classpath and as a result, completion not working.
So now the javacomplete2 plugin detects the JRE library path, thus bringing standard java completion out of the box - no configuration required!
The plugin will scan child directory tree for src directory and add it to the sources path (For this, it is nice to have vim-rooter plugin).
For the first run the plugin will compile the Javavi library.
Features
Features:
Server side java reflection class loader and parsing library;
Searches class files automatically, using maven, gradle or Eclipse's .classpath file to append completion classpath;
Generics;
Lambdas;
Annotations completion;
Nested classes;
Adding imports automatically, includes static imports and imports of nested classes;
The default mappings could be disabled with following setting:
letg:JavaComplete_EnableDefaultMappings=0
Optional
g:JavaComplete_LibsPath - path to additional jar files. This path appends with your libraries specified in pom.xml. Here you can add, for example, your glassfish libs directory or your project libs. It will be automatically append your JRE home path.
g:JavaComplete_SourcesPath - path of additional sources. Don't try to add all sources you have, this will slow down the parsing process. Instead, add your project sources and necessary library sources. If you have compiled classes add them to the previous config (g:JavaComplete_LibsPath) instead. By default the plugin will search the src directory and add it automatically.
let g:JavaComplete_MavenRepositoryDisable = 1 - don't append classpath with libraries specified in pom.xml of your project. By default is 0.
let g:JavaComplete_UseFQN = 1 - use full qualified name in completions description. By default is 0.
let g:JavaComplete_PomPath = /path/to/pom.xml - set path to pom.xml explicitly. It will be set automatically, if pom.xml is in underlying path.
let g:JavaComplete_ClosingBrace = 1 - add close brace automatically, when complete method declaration. Disable if it conflicts with another plugins.
let g:JavaComplete_JavaviLogDirectory = '' - directory, where to write server logs.
let g:JavaComplete_JavaviLogLevel = 'debug' - enables server side logging (log4j logging levels).
let g:JavaComplete_BaseDir = '~/.your_cache_dir' - set the base cache directory of javacomplete2. By default it is ~/.cache.
let g:JavaComplete_ImportDefault = 0 - the default selection of import options. By default it is 0, which means automatically select first one. To make nothing on default set -1.
let g:JavaComplete_GradleExecutable = 'gradle' - use your own path to gradle executable file.
let g:JavaComplete_ImportSortType = 'jarName' - imports sorting type. Sorting can be by jar archives jarName or by package names packageName.
let g:JavaComplete_StaticImportsAtTop = 1 - imports sorting with static imports at the top. By default this is 0.
let g:JavaComplete_ImportOrder = ['java.', 'javax.', 'com.', 'org.', 'net.'] - Specifies the order of import groups, when use packageName sorting type. An import group is a list of individual import statements that all start with the same beginning of package name surrounded by blank lines above and below the group. A * indicates all packages not specified, for 'google style' import ordering, e.g. let g:JavaComplete_ImportOrder = ['com.google.', *, 'java.', 'javax.']
let g:JavaComplete_RegularClasses = ['java.lang.String', 'java.lang.Object'] - Regular class names that will be used automatically when you insert import. You can populate it with your custom classes, or it will be populated automatically when you choose any import option. List will be persisted, so it will be used next time you run the same project.
let g:JavaComplete_CustomTemplateDirectory = '~/jc_templates' - set directory that contains custom templates, for class creation. By default this options is null.
let g:JavaComplete_AutoStartServer = 0 - Disable automatic startup of server.
let g:JavaComplete_CompletionResultSort = 1 - Sort completion results alphabetically.
let g:JavaComplete_IgnoreErrorMsg = 1 - When it is greater than 0, the error message will be ignored. By default it is 0.
let g:JavaComplete_CheckServerVersionAtStartup = 0 - Check server version on startup. Can be disabled on slow start, or infinite recompilation. By default it is 1.
let g:JavaComplete_ExcludeClassRegex = 'lombok\(\.experimental\)\?\.var' - Exclude matching fully qualified class names from producing import statements.
let g:JavaComplete_SourceExclude = ['src/frontend'] - Exclude source directories. Accept absolute and relative values.
