minify:minify

Size of the buffer used to read source files.

Specify aggregations in an external JSON formatted config file.

If a supported character set is specified, it will be used to read the input file. Otherwise, it will assume that the platform's default character set is being used. The output file is encoded using the same character set.
See the IANA Charset Registry for a list of valid encoding types.

Generate $inject properties for AngularJS for functions annotated with @ngInject.

The degree of compression and optimization to apply to your JavaScript.
There are three possible compilation levels:

• WHITESPACE_ONLY: Just removes whitespace and comments from your JavaScript.
• SIMPLE_OPTIMIZATIONS: Performs compression and optimization that does not interfere with the interaction between the compiled JavaScript and other JavaScript. This level renames only local variables.
• ADVANCED_OPTIMIZATIONS: Achieves the highest level of compression by renaming symbols in your JavaScript. When using ADVANCED_OPTIMIZATIONS compilation you must perform extra steps to preserve references to external symbols. See Advanced Compilation and Externs for more information about ADVANCED_OPTIMIZATIONS.

Collects information mapping the generated (compiled) source back to its original source for debugging purposes.
Please visit Source Map Revision 3 Proposal for more information.

Override the value of variables annotated with @define.
The format is:

<define>
    <name>value</name>
</define>

where <name> is the name of a @define variable and value is a boolean, number or string.

Determines the set of builtin externs to load.
Options: BROWSER, CUSTOM.

List of JavaScript files containing code that declares function names or other symbols. Use closureExterns to preserve symbols that are defined outside of the code you are compiling. The closureExterns parameter only has an effect if you are using a CompilationLevel of ADVANCED_OPTIMIZATIONS.
These file names are relative to webappSourceDir directory.

A whitelist of tag names in JSDoc. Needed to support JSDoc extensions like ngdoc.

Refers to which version of ECMAScript to assume when checking for errors in your code.
Possible values are:

• ECMASCRIPT3: Checks code assuming ECMAScript 3 compliance, and gives errors for code using features only present in later versions of ECMAScript.
• ECMASCRIPT5: Checks code assuming ECMAScript 5 compliance, allowing new features not present in ECMAScript 3, and gives errors for code using features only present in later versions of ECMAScript.
• ECMASCRIPT5_STRICT: Like ECMASCRIPT5 but assumes compliance with strict mode ('use strict';).
• ECMASCRIPT6: Checks code assuming ECMAScript 6 compliance, allowing new features not present in ECMAScript 5.
• ECMASCRIPT6_STRICT: Like ECMASCRIPT6 but assumes compliance with strict mode ('use strict';).

Refers to which version of ECMAScript your code will be returned in.
It accepts the same options as closureLanguageIn and is used to transpile between different levels of ECMAScript.

Enables or disables sorting mode for Closure Library dependencies.
If true, automatically sort dependencies so that a file that goog.provides symbol X will always come before a file that goog.requires symbol X.

Treat certain warnings as the specified CheckLevel:

• ERROR: Makes all warnings of the given group to build-breaking error.
• WARNING: Makes all warnings of the given group a non-breaking warning.
• OFF: Silences all warnings of the given group.

Example:

<closureWarningLevels>
    <nonStandardJsDocs>OFF</nonStandardJsDocs>
</closureWarningLevels>

Define the CSS compressor engine to use.
Possible values are:

• YUI: YUI Compressor

CSS output file name.

CSS source directory.

CSS files to exclude. Specified as fileset patterns which are relative to the CSS source directory.

CSS source file names list.

CSS files to include. Specified as fileset patterns which are relative to the CSS source directory.

CSS target directory. Takes the same value as cssSourceDir when empty.

Define the JavaScript compressor engine to use.
Possible values are:

• YUI: YUI Compressor
• CLOSURE: Google Closure Compiler

JavaScript output file name.

JavaScript source directory.

JavaScript files to exclude. Specified as fileset patterns which are relative to the JavaScript source directory.

JavaScript source file names list.

JavaScript files to include. Specified as fileset patterns which are relative to the JavaScript source directory.

JavaScript target directory. Takes the same value as jsSourceDir when empty.

Do not append a suffix to the minified output file name, independently of the value in the suffix parameter.
Warning: when both the options nosuffix and skipMerge are set to true, the plugin execution phase needs to be set to package, otherwise the output files will be overridden by the source files during the packaging.

Skip the merge step. Minification will be applied to each source file individually.

Skip the minify step. Useful when merging files that are already minified.

The output file name suffix.

Display additional informational messages and warnings.

Webapp source directory.

Webapp target directory.

Disable all the built-in micro-optimizations.

Some source control tools don't like files containing lines longer than, say 8000 characters. The line-break option is used in that case to split long lines after a specific column. It can also be used to make the code more readable and easier to debug. Specify 0 to get a line break after each semi-colon in JavaScript, and after each rule in CSS. Specify -1 to disallow line breaks.

Minify only. Do not obfuscate local symbols.

Preserve unnecessary semicolons (such as right before a '}'). This option is useful when compressed code has to be run through JSLint.
