javalin: Unable to resolve vue resources running Javalin from gradle distTar

Hi

I’ve upgraded to javalin 5.

When I dist up my javalin server into a tarball (./gradlew clean check distTar), extract it, run it and try and serve a page in non-dev mode, I see the following error:

[JettyServerThreadPool-25] WARN io.javalin.Javalin - Uncaught exception java.nio.file.NoSuchFileException: /vue at jdk.zipfs/jdk.nio.zipfs.ZipPath.getAttributes(ZipPath.java:742) at jdk.zipfs/jdk.nio.zipfs.ZipFileSystemProvider.readAttributes(ZipFileSystemProvider.java:292) at java.base/java.nio.file.Files.readAttributes(Files.java:1764) at java.base/java.nio.file.FileTreeWalker.getAttributes(FileTreeWalker.java:219) at java.base/java.nio.file.FileTreeWalker.visit(FileTreeWalker.java:276) at java.base/java.nio.file.FileTreeWalker.walk(FileTreeWalker.java:322) at java.base/java.nio.file.FileTreeIterator.<init>(FileTreeIterator.java:71) at java.base/java.nio.file.Files.walk(Files.java:3825) at io.javalin.vue.VuePathMaster.walkPaths(VuePathMaster.kt:21) at io.javalin.vue.VuePathMaster$cachedPaths$2.invoke(VuePathMaster.kt:18) at io.javalin.vue.VuePathMaster$cachedPaths$2.invoke(VuePathMaster.kt:18) at kotlin.SynchronizedLazyImpl.getValue(LazyJVM.kt:74) at io.javalin.vue.VuePathMaster.getCachedPaths$javalin(VuePathMaster.kt:18) at io.javalin.vue.VueHandler.handle(VueHandler.kt:23) at io.javalin.routing.HandlerEntry.handle(HandlerEntry.kt:19) at io.javalin.http.servlet.DefaultTasks.HTTP$lambda-8$lambda-6$lambda-5(DefaultTasks.kt:38) at io.javalin.http.servlet.JavalinServlet.handleTask(JavalinServlet.kt:86) at io.javalin.http.servlet.JavalinServlet.handleSync(JavalinServlet.kt:53) at io.javalin.http.servlet.JavalinServlet.service(JavalinServlet.kt:41) at jakarta.servlet.http.HttpServlet.service(HttpServlet.java:587) at io.javalin.jetty.JavalinJettyServlet.service(JavalinJettyServlet.kt:58) at jakarta.servlet.http.HttpServlet.service(HttpServlet.java:587) at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:764) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:529) at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:221) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:1571) at org.eclipse.jetty.server.handler.ScopedHandler.nextHandle(ScopedHandler.java:221) at io.javalin.jetty.JettyServer$start$wsAndHttpHandler$1.doHandle(JettyServer.kt:57) at org.eclipse.jetty.server.handler.ScopedHandler.nextScope(ScopedHandler.java:176) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:484) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:1544) at org.eclipse.jetty.server.handler.ScopedHandler.nextScope(ScopedHandler.java:174) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1302) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:129) at org.eclipse.jetty.server.handler.StatisticsHandler.handle(StatisticsHandler.java:173) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:122) at org.eclipse.jetty.server.Server.handle(Server.java:563) at org.eclipse.jetty.server.HttpChannel.lambda$handle$0(HttpChannel.java:505) at org.eclipse.jetty.server.HttpChannel.dispatch(HttpChannel.java:762) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:497) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:282) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:314) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:100) at org.eclipse.jetty.io.SelectableChannelEndPoint$1.run(SelectableChannelEndPoint.java:53) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:933) at org.eclipse.jetty.util.thread.QueuedThreadPool$Runner.run(QueuedThreadPool.java:1077) at java.base/java.lang.Thread.run(Thread.java:829)

I’ve been through new doco and examples to try and figure out what’s missing and I can see my app jar containing the vue resource dir therein referenced by the classpath in the gradle generated start script. I’m at somewhat of a loss as to why the vue resources are failing to resolve from the classpath when javalin needs to serve a VueComponent.

I whittled down one of the published javalin 5 examples into an example repo to illustrate the problem:

Any help/clues would be greatly appreciated.

Thanks!
