I ran into a baffling error the other day while working with Arquillian. I added Arquillian to a simple project requiring only the Java SE container for some “lite” CDI injection. However, when I went to run the unit tests, they failed:
[code lang=’java’]
org.jboss.shrinkwrap.api.exporter.ArchiveExportException: File could not be created: target/test.jar
at org.jboss.shrinkwrap.impl.base.exporter.AbstractStreamExporterImpl.getOutputStreamToFile(AbstractStreamExporterImpl.java:95)
at org.jboss.shrinkwrap.impl.base.exporter.AbstractStreamExporterImpl.exportTo(AbstractStreamExporterImpl.java:144)
at org.jboss.arquillian.container.se.managed.ManagedSEDeployableContainer.materializeArchive(ManagedSEDeployableContainer.java:294)
at org.jboss.arquillian.container.se.managed.ManagedSEDeployableContainer.deploy(ManagedSEDeployableContainer.java:191)
[/code]
This didn’t make any sense as the output directories were all writeable etc. I had another similar project that worked. Comparing both projects, I eventually added a barebones arquillian.xml config file. That did the trick! The magic appears toe be the deploymentExportPath – not sure why this is needed.
[code lang=’xml’]
