java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor

[Hantsy Bai]

Hi,

In these days, I tried to write some testing codes of Spring 6, and used cargo to deploy war to an embedded Jetty server.

My development stack is:

JakartaEE 9.10

Spring 6.0.0-M1

cargo plugin 1.9.9

Java 17

The cargo:run command raised an exception like this.

>2022-01-01 21:00:59.038:WARN :oejw.WebAppContext:Thread-2: Failed startup of context o.e.j.w.WebAppContext@2be49c8c{/demo,file:///D:/hantsylabs/spring6-sandbox/jpa/target/demo/,UNAVAIL
ABLE}{D:\hantsylabs\spring6-sandbox\jpa\target\demo.war}
java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor
        at org.eclipse.jetty.annotations.AnnotationConfiguration.createAnnotationParser(AnnotationConfiguration.

My  cargo embedded jetty is configured like this, I have tried to add asm as deps, did not work.

<profile>
<id>jetty</id>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven3-plugin</artifactId>
<version>${cargo-maven3-plugin.version}</version>
<configuration>
<container>
<containerId>jetty11x</containerId>
<type>embedded</type>
</container>
<configuration>
<properties>
<cargo.servlet.port>8080</cargo.servlet.port>
<cargo.logging>low</cargo.logging>
</properties>
</configuration>
</configuration>
<dependencies>
<dependency>
<groupId>asm</groupId>
<artifactId>asm</artifactId>
<version>3.3.1</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</profile>

The complete configuration is here:

Hi Hantsy

Happy new year!

The embedded containers have many limitations, one being that they only contain the minimal amount of dependencies and hence are unlikely to cope with complex cases without you manually adding these dependencies.

Is there a reason why you don't go for a standalone local configuration? It will be much more stable.

Thanks, switched to use `artifactInstaller` to get a copy of the jetty dist, the error disappeared.

Hi Hantsy

Excellent news 😁 The standalone local configuration comes with the advantages around configurability and packagability, while thanks to the artifactInstaller you can choose between versions of Jetty.

Enjoy!

Configured another integration test using standalone configuration, https://github.com/hantsy/spring6-sandbox/blob/master/jpa/pom.xml#L476

Hi Hantsy

Looks good, though I see the profiles jetty, tomcat and wildfly use the artifactInstaller while the profiles it-jetty, it-tomcat and it-wildfly use an extra step with the maven-dependency-plugin. Is there a reason you chose that approach?

No reason, just try different configurations, and use dependency maven plugin to download a copy to simplify configuration when running on a CI server.
