-----------------------------
Summary: Excludes tags result in unprovoked ClassNotFound
Exceptions
Key: MNG-5603
URL: https://jira.codehaus.org/browse/MNG-5603
Project: Maven 2 & 3
Issue Type: Bug
Reporter: jay vyas
My full pom file is here for reference:
https://gist.github.com/jayunit100/9644221 (this is a version of hadoop that im
playing with in the source code).
Ive found some very odd behaviour in surefire:
{noformat}
mvn test
{noformat}
With the following exclusion filter under the "excludes" tag:
{noformat}
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<systemPropertyVariables>
<startKdc>${startKdc}</startKdc>
<kdc.resource.dir>${kdc.resource.dir}</kdc.resource.dir>
</systemPropertyVariables>
<properties>
<property>
<name>listener</name>
<value>org.apache.hadoop.test.TimedOutTestsListener</value>
</property>
</properties>
<excludes>
<exclude>asbdfoin</exclude>
</excludes>
</configuration>
{noformat}
Results in an exception like this:
{noformat}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.16:test
(default-test) on project hadoop-common: Execution default-test of goal
org.apache.maven.plugins:maven-surefire-plugin:2.16:test failed:
java.lang.NoClassDefFoundError: EmptyRequestProto; nested exception is
java.lang.NoClassDefFoundError: EmptyRequestProto -> [Help 1]
{noformat}
In otherwords: Exclusion filters can result in NoClassDefFoundError messages,
when the exclusion filter doesn't match anything at all.
My question : How could the maven surefire exclusion filter cause a
ClassNotFound error to manifest ? If anything, I would expect it to REDUCE the
amount of attempts to load classes, not increase them.
FYI, some color on this: The class which is causing this "NotFound" exception
itself is an inner class:
{noformat}
public static final class EmptyRequestProto extends
com.google.protobuf.GeneratedMessage
{noformat}
I have seen SUREFIRE-988â, and possibly its related, but I the fact that my
"exclude" filter doesnt match ANY class in the code base, it might be distinct.
