Dependency contributed by cannot be found

Error message

Dependency %s contributed by %s cannot be found

What it means

CreateLombokRuntimeApp.buildRuntimeJar assembles a 'lombok-runtime.jar' by copying resources (class files plus LICENSE/AUTHORS) that are bundled inside lombok's own jar, located via Class.getResourceAsStream. If a resource the map expects is absent from the classpath, it throws Fail("Dependency %s contributed by %s cannot be found"). This normally indicates a broken/partial lombok jar build rather than user error.

Solutions

1. Use an intact official lombok jar (re-download from Project Lombok) and rerun
2. Check that CreateLombokRuntimeApp is executed from inside the lombok jar, not from loose classes on the filesystem
3. If building lombok from source, ensure the shadow/shade packaging step copies the runtime dependencies into the jar

String res = "/LICENSE";
if (CreateLombokRuntimeApp.class.getResourceAsStream(res) == null) {
    throw new IllegalStateException("Lombok jar is incomplete/corrupted: missing " + res);
}

try { app.runApp(args); } catch (Fail f) { System.err.println("Runtime jar build failed: " + f.getMessage() + " — replace lombok jar with an official build"); }

When it happens

Trigger: Running the runtime-jar creation when one of the listed resources (e.g. '/LICENSE', '/AUTHORS', or a patched runtime class like '/lombok/launch/PatchFixesShadowLoaded.class') is missing from the jar that contains CreateLombokRuntimeApp, because getResourceAsStream returns null.

Common situations: A corrupted, truncated, or repackaged lombok jar (e.g. shaded/minified by another build), running a class extracted out of the jar without its resources, or a custom/modified lombok build that dropped the bundled dependencies.
