Project.afterEvaluate throws if the project has already been evaluated, so
applying the plugin from gradle.projectsEvaluated failed. Run the deferred
configuration immediately in that case.

Read the cfVersion project property again after the build script has run, so
that a build script that applies the plugin and then defines the property is
honored.

Reading the version through a provider lets the default dependency be
computed without a reference to the extension, which the next commit needs
in order to add the dependencies from withDependencies.  Extract that
computation into defaultCFDependency, and extract the skipCheckerFramework
project property into its own method.

The project property is read both while the plugin is applied, so that the
version is correct even if a configuration is resolved while the build
script runs, and again after the build script has run, because the build
script may define the property.  Reading it only at apply time would break
a build script that sets extra["cfVersion"].

This commit does not change behavior.  Project.findProperty replaces
project.properties[...] because it states the intent more directly; both see
extra properties.

…endsFrom

extendsFrom has to be called before anything observes a source set's
configuration, but whether to add the dependencies at all depends on
excludeTests, whose value is not known that early: Gradle forbids changing a
configuration's hierarchy once the configuration has been observed.

Copy the dependencies from inside withDependencies instead, which runs when
the dependencies are queried, by which time the extension's options have
their final values.  Dependencies are copied, constraints are shared, and
exclude rules are read from the whole hierarchy; each asymmetry has a test.

Review Change Stack

📝 Walkthrough

Walkthrough

The plugin now caches project-property skip settings during task configuration and tracks other skip conditions as task inputs. Lombok task wiring uses afterEvaluateOrNow for evaluated and unevaluated projects. Functional tests cover late plugin application, skip and re-enable behavior, task invalidation, Lombok processing, and processor paths.

Merge Risk: 🟡 Moderate · up to d81ce

The plugin can capture configuration too early, causing late skip settings or option changes to be ignored and potentially omitting compiler arguments from the Lombok checker task. This may produce incorrect or incomplete Checker Framework execution, so merge should wait for fixes or explicit owner acceptance.

104-114: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Do not skip task wiring from mutable extension values.

Lines 109-114 return before dependsOn, argument providers, and doFirst are installed. If skipCheckerFramework, enabled, or excludeTests is initially disabling and a later block enables checking, the task cannot recover because Line 124 is never registered.

Only use the immutable -PskipCheckerFramework value for this early return. Evaluate all extension options in doFirst. Add regression coverage for each enabled-after-disabled transition.

Proposed fix
-      if (
-        skipCheckerFramework(skipCfProperty, cfExtension) ||
-          !cfCompileOptions.enabled.getOrElse(true) ||
-          (cfExtension.excludeTests.getOrElse(false) && isTestName(name))
-      ) {
+      if (skipCfProperty == true) {
         return@configureEach
       }

103-103: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not freeze late extra project properties at task realization.

If compileJava {} runs before project.ext.skipCheckerFramework = true, the cached value remains null, so the extra property does not override the extension setting. Defer the lookup until build-script configuration completes, or document that only invocation-time properties are supported. Add a regression test for this ordering.

Preserve late configuration ordering for the Lombok checker task.

When addCheckDelombokTask runs after project evaluation, afterEvaluateOrNow executes immediately. The separate ArrayList copy at CheckerFrameworkPlugin.kt:333 can omit compiler arguments added later in the same gradle.projectsEvaluated {} callback.

Defer this snapshot or bind the checker task to the compile task's final properties. Add a functional test for this ordering.
