Method Detail

src

void src(java.lang.Object src)
  throws java.net.MalformedURLException

Sets the download source URL

Parameters:

src - the URL

Throws:

java.net.MalformedURLException - if the download source is not a URL

dest

void dest(java.lang.Object dest)

Sets the download destination

Parameters:

dest - a file or directory where to store the retrieved file

quiet

void quiet(boolean quiet)

Sets the quiet flag

Parameters:

quiet - true if download progress should not be logged

overwrite

void overwrite(boolean overwrite)

Sets the overwrite flag

Parameters:

overwrite - true if existing files should be overwritten, false otherwise

onlyIfModified

void onlyIfModified(boolean onlyIfModified)

Sets the onlyIfModified flag

Parameters:

onlyIfModified - true if the file should only be downloaded if it has been modified on the server since the last download

onlyIfNewer

void onlyIfNewer(boolean onlyIfNewer)

Sets the onlyIfNewer flag. This method is an alias for onlyIfModified(boolean).

Parameters:

onlyIfNewer - true if the file should only be downloaded if it has been modified on the server since the last download

compress

void compress(boolean compress)

Specifies if compression should be used during download

Parameters:

compress - true if compression should be enabled

username

void username(java.lang.String username)

Sets the username for authentication

Parameters:

username - the username

password

void password(java.lang.String password)

Sets the password for authentication

Parameters:

password - the password

headers

void headers(java.util.Map<java.lang.String,java.lang.String> headers)

Sets the HTTP request headers to use when downloading

Parameters:

headers - a Map of header names to values

header

void header(java.lang.String name,
            java.lang.String value)

Sets an HTTP request header to use when downloading

Parameters:

name - name of the HTTP header

value - value of the HTTP header

acceptAnyCertificate

void acceptAnyCertificate(boolean accept)

Specifies if HTTPS certificate verification errors should be ignored and any certificate (even an invalid one) should be accepted. By default certificates are validated and errors are not being ignored.

Parameters:

accept - true if certificate errors should be ignored (default: false)

connectTimeout

void connectTimeout(int milliseconds)

Specifies the maximum time to wait in milliseconds until a connection is established. A value of zero means infinite timeout. A negative value is interpreted as undefined.

Parameters:

milliseconds - the timeout in milliseconds (default: -1)

readTimeout

void readTimeout(int milliseconds)

Specifies the maximum time in milliseconds to wait for data from the server. A value of zero means infinite timeout. A negative value is interpreted as undefined.

Parameters:

milliseconds - the timeout in milliseconds (default: -1)

retries

void retries(int retries)

Specifies the maximum number of retry attempts if a request has failed. By default, requests are never retried and the task fails immediately if the first request does not succeed.

Parameters:

retries - the maximum number of retries (default: 0)

downloadTaskDir

void downloadTaskDir(java.lang.Object dir)

Specifies the directory where gradle-download-task stores information that should persist between builds

Parameters:

dir - the directory (default: ${buildDir}/gradle-download-task)

tempAndMove

void tempAndMove(boolean tempAndMove)

Specifies whether the file should be downloaded to a temporary location and, upon successful execution, moved to the final location. If the overwrite flag is set to false, this flag is useful to avoid partially downloaded files if Gradle is forcefully closed or the system crashes. Note that the plugin always deletes partial downloads on connection errors, regardless of the value of this flag. The default temporary location can be configured with the downloadTaskDir(Object);

Parameters:

tempAndMove - true if the file should be downloaded to a temporary location and, upon successful execution, moved to the final location (default: false)

useETag

void useETag(java.lang.Object useETag)

Sets the useETag flag. Possible values are:

• true: check if the entity tag (ETag) of a downloaded file has changed and issue a warning if a weak ETag was encountered
• false: Do not use entity tags (ETags) at all
• "all": Use all ETags but do not issue a warning for weak ones
• "strongOnly": Use only strong ETags

Note that this flag is only effective if onlyIfModified is true.

Parameters:

useETag - the flag's new value

cachedETagsFile

void cachedETagsFile(java.lang.Object location)

Sets the location of the file that keeps entity tags (ETags) received from the server

Parameters:

location - the location (default: ${downloadTaskDir}/etags.json)

the onlyIfNewer flag

isCompress

Returns:

getUsername

java.lang.String getUsername()

Returns:

the username for authentication
