Convert the seven closure-based tags in RenderSitemeshTagLib (applyLayout, pageProperty, ifPageProperty, layoutTitle, layoutHead, layoutBody, content) to method handlers so GSP dispatch uses the faster reflective method-invocation path added in apache#15465 instead of cloning a closure on every invocation. This also clears the closure-based-tag deprecation warning the apache#15465 compiler check emits for this class. The conversion is behavior-preserving: GSP dispatch already passes TagOutput.EMPTY_BODY_CLOSURE (never null) as the body to two-arg tags, so the existing body checks resolve identically whether the tag is a closure field or a method. Sitemesh3LayoutTagLib is intentionally left as closures, matching its SiteMesh 2 twin GrailsLayoutTagLib: those grailsLayout-namespace, @CompileStatic capture tags driven by GrailsLayoutPreprocessor were deliberately kept as closures in apache#15465. Follow-up to apache#15713. Addresses review feedback on RenderSitemeshTagLib.
Bump the SiteMesh 3 dependencies (spring-boot-starter-sitemesh and spring-webmvc-sitemesh, plus the transitive sitemesh core) from 3.3.0-SNAPSHOT to the released 3.3.0-M1 milestone, now available on Maven Central. SiteMesh 2 (opensymphony:sitemesh 2.6.0, used by grails-layout) is unaffected.

… handlers Convert the seven closure-based capture tags in Sitemesh3LayoutTagLib (captureHead, captureBody, captureTitle, wrapTitleTag, captureMeta, captureContent, parameter) to method handlers, completing the SiteMesh 3 plugin's move off closure-based tags so both shipped taglibs use the faster method-invocation path and the apache#15465 closure-tag deprecation warning is cleared for the whole plugin. These grailsLayout-namespace capture tags are emitted by GrailsLayoutPreprocessor and dispatched through GroovyPage.invokeTag, which already routes to method handlers (invokeTagLibMethod -> TagMethodInvoker) and passes a non-null EMPTY_BODY_CLOSURE body, so the conversion is behavior-preserving even though the class is @CompileStatic. Verified by the gsp-sitemesh3 EndToEndSpec integration suite (14 tests, all passing) against SiteMesh 3.3.0-M1.

Address review feedback on apache#15710: the sitemesh snapshot-repository version filter does not need to match -SNAPSHOT explicitly, because the repository is already constrained to snapshots (snapshotsOnly: true in CreateAppCommand, VersionType.SNAPSHOT in GradleRepository). Simplify the version regex from '.*-SNAPSHOT' to '.*' in both the forge generator and the shell-cli create-app command, matching how the version type is set.

Is the M1 and actual release? I don't think this code should change since the below filter will still filter to only snapshots

@jdaugherty per @matrei it's redundant and not needed. #15710

Summary
Follow-up to #15713, addressing review feedback on
RenderSitemeshTagLib:Converts both taglibs shipped by the SiteMesh 3 plugin from closure-based tags to the method handlers introduced in #15465, so GSP dispatch uses the faster reflective method-invocation path instead of cloning a closure on every tag invocation. This also clears the closure-based-tag deprecation warning the #15465 compiler check emits for these classes.
RenderSitemeshTagLib(sitemeshnamespace) —applyLayout,pageProperty,ifPageProperty,layoutTitle,layoutHead,layoutBody,content.Sitemesh3LayoutTagLib(grailsLayoutnamespace,@CompileStatic) — the compile-time capture tagscaptureHead,captureBody,captureTitle,wrapTitleTag,captureMeta,captureContent,parameter. These are emitted byGrailsLayoutPreprocessorand dispatched throughGroovyPage.invokeTag, which already routes to method handlers (invokeTagLibMethod→TagMethodInvoker).After this change, no taglib used by the SiteMesh 3 plugin remains closure-based.
Behavior preservation
Only the tag declarations change; the tag bodies are untouched. Both the closure and method dispatch paths (
TagOutput.captureTagOutputandGroovyPage.invokeTag) share the same output-stack setup and already passTagOutput.EMPTY_BODY_CLOSURE(nevernull) as the body to two-argument tags, so the existingbody/body instanceof Closurechecks resolve identically whether each tag is a closure field or a method.SiteMesh 3.3.0-M1
Also bumps the SiteMesh 3 dependencies (
spring-boot-starter-sitemesh,spring-webmvc-sitemesh, and the transitiveorg.sitemesh:sitemeshcore) from3.3.0-SNAPSHOTto the released 3.3.0-M1 milestone, now on Maven Central. SiteMesh 2 (opensymphony:sitemesh2.6.0, used bygrails-layout) is unaffected.Tests

Addresses two review comments on #15710: the generated-app sitemesh snapshot repository's version filter does not need to match
-SNAPSHOTexplicitly, because the repository is already constrained to snapshots —snapshotsOnly: trueinCreateAppCommandandVersionType.SNAPSHOTinGradleRepository. The version regex is simplified from.*-SNAPSHOTto.*in both places. (The pre-existing apache/groovy snapshot filters are left untouched.)
