MultiException[java.lang.RuntimeException: Error scanning file]
Case
I run a project with JSF 2 / PrimeFaces 5 (BTW: it rocks!) / Spring 4 / Jetty 9 / Java 8:
MultiException java.lang.RuntimeException: Error scanning file SummerBean.class, java.lang.RuntimeException: Error scanning entry .../SummerService.class from jar file:/.../spring-tier-1.0-SNAPSHOT.jar, java.lang.RuntimeException: Error scanning entry .../SummerServiceImpl.class from jar file:/.../spring-tier-1.0-SNAPSHOT.jar at org.eclipse.jetty.annotations.AnnotationConfiguration.scanForAnnotations(AnnotationConfiguration.java:530)
Explanation
The error occurs because of a conflict on the JARs of ASM.
Fix
You have to override Jetty’s dependencies to ASM.
In Maven’s POM, amend Jetty plugin to force ASM versions:
<plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>${jetty.version}</version> <dependencies> <dependency> <groupId>org.ow2.asm</groupId> <artifactId>asm</artifactId> <version>5.0.2</version> </dependency> <dependency> <groupId>org.ow2.asm</groupId> <artifactId>asm-commons</artifactId> <version>5.0.2</version> </dependency> </dependencies> <!-- ... --> </plugin>
Then it should work 😉
