Maven War plugin

war:war

Full name:

org.apache.maven.plugins:maven-war-plugin:2.3:war

Description:

Build a WAR file.

Attributes:

Requires a Maven project to be executed.
Requires dependency resolution of artifacts in scope: runtime.
The goal is thread-safe and supports parallel builds.
Binds by default to the lifecycle phase: package.

Required Parameters

Name	Type	Since	Description
cacheFile	`File`	`2.1-alpha-1`	The file containing the webapp structure cache. Default value is: `${project.build.directory}/war/work/webapp-cache.xml`.
outputDirectory	`String`	`-`	The directory for the generated WAR. Default value is: `${project.build.directory}`.
warName	`String`	`-`	The name of the generated WAR. Default value is: `${project.build.finalName}`.
warSourceDirectory	`File`	`-`	Single directory for extra files to include in the WAR. This is where you place your JSP files. Default value is: `${basedir}/src/main/webapp`.
webappDirectory	`File`	`-`	The directory where the webapp is built. Default value is: `${project.build.directory}/${project.build.finalName}`.
workDirectory	`File`	`-`	Directory to unpack dependent WARs into if needed. Default value is: `${project.build.directory}/war/work`.

Optional Parameters

Name	Type	Since	Description
archive	`MavenArchiveConfiguration`	`-`	The archive configuration to use. See Maven Archiver Reference.
archiveClasses	`boolean`	`2.0.1`	Whether a JAR file will be created for the classes in the webapp. Using this optional configuration parameter will make the compiled classes to be archived into a JAR file and the classes directory will then be excluded from the webapp. Default value is: `false`. User property is: `archiveClasses`.
attachClasses	`boolean`	`2.1-alpha-2`	Whether classes (that is the content of the WEB-INF/classes directory) should be attached to the project as an additional artifact. By default the classifier for the additional artifact is 'classes'. You can change it with the `<classesClassifier>someclassifier</classesClassifier>` parameter. If this parameter true, another project can depend on the classes by writing something like: <dependency> <groupId>myGroup</groupId> <artifactId>myArtifact</artifactId> <version>myVersion</myVersion> <classifier>classes</classifier> </dependency> Default value is: `false`.
classesClassifier	`String`	`2.1-alpha-2`	The classifier to use for the attached classes artifact. Default value is: `classes`.
classifier	`String`	`-`	Classifier to add to the generated WAR. If given, the artifact will be an attachment instead. The classifier will not be applied to the JAR file of the project - only to the WAR file.
containerConfigXML	`File`	`-`	The path to a configuration file for the servlet container. Note that the file name may be different for different servlet containers. Apache Tomcat uses a configuration file named context.xml. The file will be copied to the META-INF directory. User property is: `maven.war.containerConfigXML`.
dependentWarExcludes	`String`	`-`	Deprecated. Use <overlay>/<excludes> instead
dependentWarIncludes	`String`	`-`	Deprecated. Use <overlay>/<includes> instead
escapeString	`String`	`2.1-beta-1`	Expression preceded with this String won't be interpolated. `\${foo}` will be replaced with `${foo}`. User property is: `maven.war.escapeString`.
escapedBackslashesInFilePath	`boolean`	`2.1-alpha-2`	To escape interpolated values with Windows path `c:\foo\bar` will be replaced with `c:\\foo\\bar`. Default value is: `false`. User property is: `maven.war.escapedBackslashesInFilePath`.
failOnMissingWebXml	`boolean`	`2.1-alpha-2`	Whether or not to fail the build if the `web.xml` file is missing. Set to `false` if you want you WAR built without a `web.xml` file. This may be useful if you are building an overlay that has no web.xml file. Default value is: `true`. User property is: `failOnMissingWebXml`.
filteringDeploymentDescriptors	`boolean`	`2.1-alpha-2`	To filter deployment descriptors. Disabled by default. Default value is: `false`. User property is: `maven.war.filteringDeploymentDescriptors`.
filters	`List`	`-`	Filters (property files) to include during the interpolation of the pom.xml.
nonFilteredFileExtensions	`List`	`2.1-alpha-2`	A list of file extensions that should not be filtered. Will be used when filtering webResources and overlays.
outputFileNameMapping	`String`	`2.1-alpha-1`	The file name mapping to use when copying libraries and TLDs. If no file mapping is set (default) the files are copied with their standard names.
overlays	`List`	`2.1-alpha-1`	The overlays to apply. Each <overlay> element may contain: id (defaults to `currentBuild`) groupId (if this and artifactId are null, then the current project is treated as its own overlay) artifactId (see above) classifier type includes (a list of string patterns) excludes (a list of string patterns) filtered (defaults to false) skip (defaults to false) targetPath (defaults to root of webapp structure)
packagingExcludes	`String`	`2.1-alpha-2`	The comma separated list of tokens to exclude from the WAR before packaging. This option may be used to implement the skinny WAR use case. Note that you can use the Java Regular Expressions engine to include and exclude specific pattern using the expression %regex[]. Hint: read the about (?!Pattern).
packagingIncludes	`String`	`2.1-beta-1`	The comma separated list of tokens to include in the WAR before packaging. By default everything is included. This option may be used to implement the skinny WAR use case. Note that you can use the Java Regular Expressions engine to include and exclude specific pattern using the expression %regex[].
primaryArtifact	`boolean`	`-`	Whether this is the main artifact being built. Set to `false` if you don't want to install or deploy it to the local repository instead of the default one in an execution. Default value is: `true`. User property is: `primaryArtifact`.
recompressZippedFiles	`boolean`	`2.3`	Indicates if zip archives (jar,zip etc) being added to the war should be compressed again. Compressing again can result in smaller archive size, but gives noticeably longer execution time. Default value is: `false`.
resourceEncoding	`String`	`2.3`	The encoding to use when copying filtered web resources. Default value is: `${project.build.sourceEncoding}`. User property is: `resourceEncoding`.
useCache	`boolean`	`2.1-alpha-1`	Whether the cache should be used to save the status of the webapp across multiple runs. Experimental feature so disabled by default. Default value is: `false`. User property is: `useCache`.
