Interface RepositorySystemSession.SessionBuilder

Enclosing interface:

RepositorySystemSession

public static interface RepositorySystemSession.SessionBuilder

Builder for building RepositorySystemSession.CloseableSession instances. Builder instances can be created with RepositorySystem.createSessionBuilder() method. Instances are not thread-safe nor immutable.

Important: if you set a stateful member on builder (for example SessionData or RepositoryCache), the builder will create session instances using same provided stateful members, that may lead to unexpected side effects. Solution for these cases is to not reuse builder instances, or, keep reconfiguring it, or ultimately provide suppliers that create new instance per each call.

Since:

2.0.0

Restriction:

This interface is not intended to be extended by clients.

Method Details

setOffline

RepositorySystemSession.SessionBuilder setOffline(boolean offline)

Controls whether the repository system operates in offline mode and avoids/refuses any access to remote repositories.

Parameters:

offline - true if the repository system is in offline mode, false otherwise.

Returns:

This session for chaining, never null.

setIgnoreArtifactDescriptorRepositories

RepositorySystemSession.SessionBuilder setIgnoreArtifactDescriptorRepositories(boolean ignoreArtifactDescriptorRepositories)

Controls whether repositories declared in artifact descriptors should be ignored during transitive dependency collection. If enabled, only the repositories originally provided with the collect request will be considered.

Parameters:

ignoreArtifactDescriptorRepositories - true to ignore additional repositories from artifact descriptors, false to merge those with the originally specified repositories.

Returns:

This session for chaining, never null.

setResolutionErrorPolicy

RepositorySystemSession.SessionBuilder setResolutionErrorPolicy(ResolutionErrorPolicy resolutionErrorPolicy)

Sets the policy which controls whether resolutions errors from remote repositories should be cached.

Parameters:

resolutionErrorPolicy - The resolution error policy for this session, may be null if resolution errors should generally not be cached.

Returns:

This session for chaining, never null.

setArtifactDescriptorPolicy

RepositorySystemSession.SessionBuilder setArtifactDescriptorPolicy(ArtifactDescriptorPolicy artifactDescriptorPolicy)

Sets the policy which controls how errors related to reading artifact descriptors should be handled.

Parameters:

artifactDescriptorPolicy - The descriptor error policy for this session, may be null if descriptor errors should generally not be tolerated.

Returns:

This session for chaining, never null.

setChecksumPolicy

RepositorySystemSession.SessionBuilder setChecksumPolicy(String checksumPolicy)

Sets the global checksum policy. If set, the global checksum policy overrides the checksum policies of the remote repositories being used for resolution.

Parameters:

checksumPolicy - The global checksum policy, may be null/empty to apply the per-repository policies.

Returns:

This session for chaining, never null.

• RepositoryPolicy.CHECKSUM_POLICY_FAIL
• RepositoryPolicy.CHECKSUM_POLICY_IGNORE

setUpdatePolicy

RepositorySystemSession.SessionBuilder setUpdatePolicy(String updatePolicy)

Sets the global update policy. If set, the global update policy overrides the update policies of the remote repositories being used for resolution.

This method is meant for code that does not want to distinguish between artifact and metadata policies. Note: applications should either use get/set updatePolicy (this method and RepositorySystemSession.getUpdatePolicy()) or also distinguish between artifact and metadata update policies (and use other methods), but should not mix the two!

Parameters:

updatePolicy - The global update policy, may be null/empty to apply the per-repository policies.

Returns:

This session for chaining, never null.
