apache ivy settings

Apache Ivy settings are configuration files that control the behavior of Ivy. There are two main types of Ivy settings: global settings and project-specific settings.

Global Settings:

Global settings apply to all Ivy projects on a given machine. These settings are stored in the ivysettings.xml file, which is typically located in the Ivy home directory. Here are some common global settings:

  1. Resolvers: Global resolvers define the repositories that Ivy can use to download modules. By default, Ivy comes with a few resolvers, including the local filesystem, a URL resolver, and a Maven resolver.

  2. Cache settings: The global cache settings define how Ivy stores downloaded modules and metadata in the local cache. You can configure the maximum size of the cache, the location of the cache directory, and the expiration time for cached items.

  3. Proxy settings: If you are behind a proxy, you can configure Ivy to use the proxy server to download modules. You can specify the proxy server's host, port, username, and password.

  4. Dependency exclusions: You can specify global dependency exclusions, which will exclude certain transitive dependencies from all projects.

Project-specific Settings:

Project-specific settings apply only to a specific Ivy project. These settings are stored in the ivy.xml file, which is typically located in the root directory of the project. Here are some common project-specific settings:

  1. Module settings: The module settings specify the name, organization, and version of the current project, as well as any other metadata that should be included in the module descriptor.

  2. Dependency declarations: The dependency declarations specify the dependencies that the project requires, including the module name, organization, and version. You can also specify exclusions for specific dependencies, or use transitive="false" to disable transitive dependency resolution.

  3. Configuration settings: The configuration settings specify named sets of dependencies that are used for specific tasks, such as compiling, testing, or running the application. You can specify which dependencies should be included in each configuration, and you can also create custom configurations to suit your project's needs.

  4. Publish settings: The publish settings specify how the project should be published to a repository, including the repository URL, credentials, and artifact patterns.

By configuring these settings, you can control how Ivy resolves dependencies, where it looks for modules, how it caches downloaded items, and how it publishes your project to a repository.
