Вы можете написать собственное правило для плагина maven -forcer, как описано в
http://maven.apache.org/enforcer/enforcer-api/writing-a-custom-rule.html
Вот как я это сделал.
NoPackageCyclesRule.java
package org.apache.maven.enforcer.rule;
import java.io.File;
import java.io.IOException;
import jdepend.framework.JDepend;
import org.apache.maven.enforcer.rule.api.EnforcerRule;
import org.apache.maven.enforcer.rule.api.EnforcerRuleException;
import org.apache.maven.enforcer.rule.api.EnforcerRuleHelper;
import org.apache.maven.plugin.logging.Log;
import org.apache.maven.project.MavenProject;
import org.codehaus.plexus.component.configurator.expression.ExpressionEvaluationException;
public class NoPackageCyclesRule implements EnforcerRule
{
public void execute(EnforcerRuleHelper helper) throws EnforcerRuleException
{
Log log = helper.getLog();
try
{
MavenProject project = (MavenProject) helper.evaluate("${project}");
File targetDir = new File((String) helper.evaluate("${project.build.directory}"));
File classesDir = new File(targetDir, "classes");
if (project.getPackaging().equalsIgnoreCase("jar") && classesDir.exists())
{
JDepend jdepend = new JDepend();
jdepend.addDirectory(classesDir.getAbsolutePath());
jdepend.analyze();
if (jdepend.containsCycles())
{
throw new EnforcerRuleException("There are package cycles");
}
}
else
{
log.warn("Skipping jdepend analysis as " + classesDir + " does not exist.");
}
}
catch (ExpressionEvaluationException e)
{
throw new EnforcerRuleException("Unable to lookup an expression "
+ e.getLocalizedMessage(), e);
}
catch (IOException e)
{
throw new EnforcerRuleException("Unable to access target directory "
+ e.getLocalizedMessage(), e);
}
}
public String getCacheId()
{
return "";
}
public boolean isCacheable()
{
return false;
}
public boolean isResultValid(EnforcerRule arg0)
{
return false;
}
}
