Errors with snapshot version on JBoss EAP #111

Open hvico opened 8 years ago

hvico commented 8 years ago

Hello,

I've trying to setup hotswap agent for a project, which is a MAVEN multi-module EAR project (JSF/PrimeFaces, Hibernate, Weld, patched JRE 1.7.0u79, and the IDE is Eclipse). The ear is deployed on JBoss EAP 6.3 (JBoss AS 7).

I specified the "target" output directories in Eclipse as extraClasspath in hotswap-agent.properties in order to override the classes bundled at the EAR.

Using the stable version (0.3) of hotswap-agent I get classloader errors, the ones reported at this issue.

Using the latest snapshot I get other sort of errors deploying the app. These are:

(after JBossModulesPlugin initialization) InvocationTargetException in transform method on plugin 'class org.hotswap.agent.plugin.weld.WeldPlugin' class 'org/jboss/weld/bean/proxy/ProxyFactory'.

Caused by: org.hotswap.agent.javassist.CannotCompileException: [source error] no such field: beanArchiveType at org.hotswap.agent.javassist.CtBehavior.insertAfter(CtBehavior.java:841) at org.hotswap.agent.javassist.CtBehavior.insertAfter(CtBehavior.java:759) at org.hotswap.agent.plugin.weld.BeanDeploymentArchiveTransformer.transformJbossBda(BeanDeploymentArchiveTransformer.java:80)

HHH000274: Unable to apply constraints on DDL for: com.somecompany.SomeEntity java.lang.IllegalArgumentException: Plugin not found in the registry org.hotswap.agent.plugin.hibernate.HibernatePlugin@3ecc25ad

(after Hibernate plugin initialization which occurs much later than the previous error) InvocationTargetException in transform method on plugin 'class org.hotswap.agent.plugin.weld.WeldPlugin' class 'org/jboss/as/weld/deployment/BeanDeploymentArchiveImpl'. ..... Caused by: org.hotswap.agent.javassist.NotFoundException: no such constructor at org.hotswap.agent.javassist.CtClass.getConstructor(CtClass.java:883)

Thanks,

You have probably unsupported version of Weld. WeldPlugin supports versions >=8.x.

Look at https://github.com/HotswapProjects/HotswapAgent/blob/master/plugin/hotswap-agent-weld-plugin/run-tests.sh . But I didn't check the v3.0 till now.

Which versions of Weld are supported? I thought that Weld is only at version 3.
