Stephan202 opened a new issue, #934: URL: https://github.com/apache/maven-enforcer/issues/934
### New feature, improvement proposal We have a large multi-module build with quite a number of built-in and [extra](https://github.com/mojohaus/extra-enforcer-rules) enforcer rules enabled. For modules with many dependencies, plugin execution takes several seconds, adding up to hundreds of seconds over-all. Based on some profiling, most time is spent repeatedly collecting dependency information: <img width="1835" height="735" alt="Image" src="https://github.com/user-attachments/assets/817eac46-4a30-45ed-ab3e-13c7cf8f3384"; /> I had a brief look at the code, and besides [full rule caching](https://github.com/apache/maven-enforcer/blob/ee5abeeabba6acad11b3b5ba279def0ab6c1f80c/maven-enforcer-plugin/src/main/java/org/apache/maven/plugins/enforcer/internal/EnforcerRuleCache.java#L57) it appears that dependency resolution isn't cached. Would it be possible to add this, such that distinct rules applied to the same module can reuse invariant dependency information? --- I suppose that the changes in #930 could be extended to support more fine-grained caching ([`AbstractResolveDependencies#collectProjectDependencies()`](https://github.com/mojohaus/extra-enforcer-rules/blob/1faa3fec2f557c289339c6dd78ff945355a74e7d/src/main/java/org/codehaus/mojo/extraenforcer/dependencies/AbstractResolveDependencies.java#L92) would be an easy candidate), but [`SessionData`](https://maven.apache.org/resolver/apidocs/org/eclipse/aether/SessionData.html)'s documentation explicitly states: > Unlike a cache, this session data is not subject to purging. For this same reason, session data should also not be abused as a cache (i.e. for storing values that can be re-calculated) to avoid memory exhaustion. There's also [`EnforcerRuleHelper#getCache(String key, Supplier<?> producer)`](https://github.com/apache/maven-enforcer/blob/ee5abeeabba6acad11b3b5ba279def0ab6c1f80c/enforcer-api/src/main/java/org/apache/maven/enforcer/rule/api/EnforcerRuleHelper.java#L126), but `EnforcerRuleHelper` is deprecated. I can't promise to have time in the near feature to help implement any improvement in this area, but if one were to attempt this, what would be the recommended approach? -- This is an automated message from the Apache Git Service.
