Summary: LinkageError
org.apache.maven.surefire.shade.org.apache.maven.shared.utils.io.IOUtil
Key: SUREFIRE-1071
URL: https://jira.codehaus.org/browse/SUREFIRE-1071
Project: Maven Surefire
Issue Type: Bug
Components: Maven Surefire Plugin
Affects Versions: 2.16
Environment: Maven 3.1.1 and Maven 3.2.1
Reporter: Julian Payne

Every so often when I am running the unit tests on a standard Maven project I
get a linkage error:
[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ asf-maven-

This error is not reproducible but I am getting it from time to time when
running maven on the command line as well as in my Jenkins jobs that are
running Maven jobs.
When this LinkageError occurs the maven run blocks.
This is what I have in the effective pom for the run above that blocked:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<inherited>true</inherited>
<configuration>
<argLine>-Xms768m -Xmx768m</argLine>
<trimStackTrace>true</trimStackTrace>
<childDelegation>false</childDelegation>
<classpathDependencyExcludes>
<classpathDependencyExclude>org.dom4j:dom4j</classpathDependencyExclude>
</classpathDependencyExcludes>
</configuration>
</plugin>
Thanks,
Julian Payne
