public class Wrapper
extends DefaultTask

Generates scripts (for *nix and windows) which allow you to build your project with Gradle, without having to install Gradle.

When a user executes a wrapper script the first time, the script downloads and installs the appropriate Gradle distribution and runs the build against this downloaded distribution. Any installed Gradle distribution is ignored when using the wrapper scripts.

The scripts generated by this task are intended to be committed to your version control system. This task also generates a small gradle-wrapper.jar bootstrap JAR file and properties file which should also be committed to your VCS. The scripts delegates to this JAR.

Method Detail

getFileLookup

@Inject
protected org.gradle.api.internal.file.FileLookup getFileLookup()

getScriptFile

@OutputFile
public File getScriptFile()

Returns the file to write the wrapper script to.

setScriptFile

public void setScriptFile(Object scriptFile)

getBatchScript

@OutputFile
public File getBatchScript()

Returns the file to write the wrapper batch script to.

getJarFile

@OutputFile
public File getJarFile()

Returns the file to write the wrapper jar file to.

setJarFile

public void setJarFile(Object jarFile)

getPropertiesFile

@OutputFile
public File getPropertiesFile()

Returns the file to write the wrapper properties to.

getDistributionPath

public String getDistributionPath()

Returns the path where the gradle distributions needed by the wrapper are unzipped. The path is relative to the distribution base directory

See Also:

setDistributionPath(String)

setDistributionPath

public void setDistributionPath(String distributionPath)

Sets the path where the gradle distributions needed by the wrapper are unzipped. The path is relative to the distribution base directory

See Also:

setDistributionPath(String)

getGradleVersion

public String getGradleVersion()

Returns the gradle version for the wrapper.

See Also:

setGradleVersion(String)

setGradleVersion

public void setGradleVersion(String gradleVersion)

The version of the gradle distribution required by the wrapper. This is usually the same version of Gradle you use for building your project.

getDistributionUrl

@Input
public String getDistributionUrl()

The URL to download the gradle distribution from.

If not set, the download URL is the default for the specified getGradleVersion().

If getGradleVersion() is not set, will return null.

The wrapper downloads a certain distribution only once and caches it. If your distribution base is the project, you might submit the distribution to your version control system. That way no download is necessary at all. This might be in particular interesting, if you provide a custom gradle snapshot to the wrapper, because you don't need to provide a download server then.

setDistributionUrl

public void setDistributionUrl(String url)

getDistributionBase

public Wrapper.PathBase getDistributionBase()

The distribution base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.

setDistributionBase

public void setDistributionBase(Wrapper.PathBase distributionBase)

The distribution base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.

getArchivePath

public String getArchivePath()

Returns the path where the gradle distributions archive should be saved (i.e. the parent dir). The path is relative to the archive base directory.

setArchivePath

public void setArchivePath(String archivePath)

Set's the path where the gradle distributions archive should be saved (i.e. the parent dir). The path is relative to the parent dir specified with getArchiveBase().

getArchiveBase

public Wrapper.PathBase getArchiveBase()

The archive base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.

setArchiveBase

public void setArchiveBase(Wrapper.PathBase archiveBase)

The archive base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.
