Description
As reported by @AaronRegan , we are unable to resolve transitive dependencies in extension jars.
- Steps to reproduce
Given a maven module containing a custom mailet, instanciating objects as part of the service method that are NOT part of James classpath:
- 1. Start any James guice application
- 2. Drop the JAR of the aforementioned in extension-jars folder
- 3. Configure the mailet within the mailet pipeline
- 4. Process a mail and....
- 5. Notice runtime failures! The service method does not succeed to instanciate the object not being part of James classpath.
As off commit 42d7d55d5380d13648533160844d30f765a2c6f1, such a JAR could very well be the apache-mailet-crypto JAR.
This would result in :
java.lang.ClassNotFoundException: org.bouncycastle.mail.smime.SMIMESignedGenerator at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 82 common frames omitted Wrapped by: java.lang.NoClassDefFoundError: org/bouncycastle/mail/smime/SMIMESignedGenerator at org.apache.james.transport.SMIMEKeyHolder.createGenerator(SMIMEKeyHolder.java:208) at org.apache.james.transport.SMIMEKeyHolder.generate(SMIMEKeyHolder.java:251) at org.apache.james.transport.mailets.AbstractSign.service(AbstractSign.java:486) at org.apache.james.mailetcontainer.impl.camel.CamelProcessor.process(CamelProcessor.java:81) at org.apache.james.mailetcontainer.impl.camel.CamelMailetProcessor$MailetContainerRouteBuilder.handleMailet(CamelMailetProcessor.java:178) at org.apache.james.mailetcontainer.impl.camel.CamelMailetProcessor$MailetContainerRouteBuilder.lambda$configure$0(CamelMailetProcessor.java:155) at org.apache.camel.processor.DelegateSyncProcessor.process(DelegateSyncProcessor.java:63) ... 75 common frames omitted
- What to do from here
- Write a test reproducing that behavior...
- Bundle apache-mailet-crypto within supported guice app mailets
- Fix that annoying transitive dependency issue - this is in my opinion a blocker for Guice adoption.
