Structs1.18Minimum Jenkins requirement: 2.60.3ID: structs
Jenkins has many DSL like plugins that require having short concise names for implementations of the extension points and other Jenkins objects. For example, Job DSL Plugin refers to each
SCM extension by its short name. The same goes for pipeline plugin.
It benefits users that these DSL plugins use consistent names. This plugin, together with the
@Symbol annotation, allow plugin developers to name their extension and have all the DSL plugins recognize them.
Usage for developers creating any plugins
To allow all the DSL plugins to refer to your extensions by the same name, put
@Symbol annotation along side your
@Extension. The symbol name must be a valid Java identifier, and it should be short and concise. To keep the symbol name short, it needs to be only unique within the extension point. For example,
GitToolInstaller should both have a symbol name
git, because they are from different extension points. For compatibility reasons with DSL plugins that predates the structs plugin, some extensions may have legacy names that do not follow this convention.
If you are targeting 1.x version of Jenkins, you must also add the following dependency to your plugin POM:
Usage for DSL plugin developers
Look up an extension by its symbol:

- Hotfix for sigh Groovy-related madness, partially reverting memory optimizations from 1.12
- Minor correction to DescribableModel caching lookup
- Eliminates any risk looking up DescribableModels if different plugins somehow define identical but incompatible Describable classes in the same package and class
Version 1.12 (Feb 1, 2018)
- Major Optimizations:
- Cache negative-hits in Symbol lookup (i.e. "no match"), eliminating needless classloading and iteration over classes.
- Cache DescribableModels, eliminating classloading associated with creation.
- Net result: huge reduction in disk reads, lock contention (classloading), CPU use, and memory garbage generated.
- Minor optimization: reduce memory use and garbage generation (collection pre-sizing and use of Singleton collections)
