maven_artifact - Downloads an Artifact from a Maven Repository

New in version 2.0.

Synopsis

  • Downloads an artifact from a maven repository given the maven coordinates provided to the module.
  • Can retrieve snapshots or release versions of the artifact and will resolve the latest available version if one is not available.

Requirements

The below requirements are needed on the host that executes this module.

  • lxml
  • boto if using a S3 repository (s3://…)

Parameters

Parameter
Choices/Defaults
Comments
artifact_id
required
The maven artifactId coordinate
attributes
(added in 2.3)
Attributes the file or directory should have. To get supported flags look at the man page for chattr on the target system. This string should contain the attributes in the same order as the one displayed by lsattr.

aliases: attr
classifier
The maven classifier coordinate
dest
required
The path where the artifact should be written to
If file mode or ownerships are specified and destination path already exists, they affect the downloaded file
extension
Default:
jar
The maven type/extension coordinate
group
Name of the group that should own the file/directory, as would be fed to chown.
group_id
required
The Maven groupId coordinate
keep_name
(added in 2.4)
    Choices:
  • no ←
  • yes
If yes, the downloaded artifact's name is preserved, i.e the version number remains part of it.
This option only has effect when dest is a directory and version is set to latest.
mode
Mode the file or directory should be. For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either specify the leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '0644' so Ansible receives a string and can do its own conversion from string into number. Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of version 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r).
owner
Name of the user that should own the file/directory, as would be fed to chown.
password
The password to authenticate with to the Maven Repository. Use AWS secret access key of the repository is hosted on S3

aliases: aws_secret_access_key
repository_url
Default:
http://repo1.maven.org/maven2
The URL of the Maven Repository to download from.
Use s3://... if the repository is hosted on Amazon S3, added in version 2.2.
Use file://... if the repository is local, added in version 2.6
selevel
Default:
s0
Level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the range. _default feature works as for seuser.
serole
Role part of SELinux file context, _default feature works as for seuser.
setype
Type part of SELinux file context, _default feature works as for seuser.
seuser
User part of SELinux file context. Will default to system policy, if applicable. If set to _default, it will use the user portion of the policy if available.
state
    Choices:
  • present ←
  • absent
The desired state of the artifact
timeout
(added in 2.3)
Default:
10
Specifies a timeout in seconds for the connection attempt
unsafe_writes
(added in 2.2)
    Choices:
  • no ←
  • yes
Normally this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, sometimes systems are configured or just broken in ways that prevent this. One example are docker mounted files, they cannot be updated atomically and can only be done in an unsafe manner.
This boolean option allows ansible to fall back to unsafe methods of updating files for those cases in which you do not have any other choice. Be aware that this is subject to race conditions and can lead to data corruption.
username
The username to authenticate as to the Maven Repository. Use AWS secret key of the repository is hosted on S3

aliases: aws_secret_key
validate_certs
(added in 1.9.3)
    Choices:
  • no
  • yes ←
If no, SSL certificates will not be validated. This should only be set to no when no other option exists.
verify_checksum
(added in 2.6)
    Choices:
  • never
  • download ←
  • change
  • always
If never, the md5 checksum will never be downloaded and verified.
If download, the md5 checksum will be downloaded and verified only after artifact download. This is the default.
If change, the md5 checksum will be downloaded and verified if the destination already exist, to verify if they are identical. This was the behaviour before 2.6. Since it downloads the md5 before (maybe) downloading the artifact, and since some repository software, when acting as a proxy/cache, return a 404 error if the artifact has not been cached yet, it may fail unexpectedly. If you still need it, you should consider using always instead - if you deal with a checksum, it is better to use it to verify integrity after download.
always combines download and change.
version
Default:
latest
The maven version coordinate

Status

This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
