The duplicate finder plugin ignores the following classpath elements by default unless the useDefaultResourceIgnoreList flag is set to false.
| Regular expression | Description |
|---|---|
^META-INF/.* |
matches any resource inside a META-INF directory in the classpath hierarchy root. Jars store information in META-INF and some resources actually must be on the classpath multiple times (e.g. for the Java Service Provider facility). |
^OSGI-INF/.* |
matches any resource inside an OSGI-INF directory in the classpath hierarchy root. OSGi components store their information in this directory. |
^licenses/.* |
matches any resource inside a licenses directory in the classpath hierarchy root. This is a common place for storing component specific license resources which often have the same name. |
.*license(\.txt)?$ |
matches any resource ending in license or license.txt. This is a common name for license resources which tend to get sprinkled all across dependencies. |
.*notice(\.txt)?$ |
matches any resource ending in notice or notice.txt. This is a common name for resources (e.g. in Apache provided jars) which tend to get sprinkled all across dependencies. |
.*readme(\.txt)?$ |
matches any resource ending in readme or readme.txt. This is a common name for component information which tend to get sprinkled all across dependencies. |
.*third-party(\.txt)?$ |
matches any resource ending in third-party or third-party.txt. This is a common name for resources (e.g. in Apache provided jars) which tend to get sprinkled all across dependencies. |
.*package\.html$ |
matches any resource ending in package.html. The old name of package-info.java which tend to get sprinkled across jars and then clash if a package is populated from multiple jars. |
.*overview\.html$ |
matches any resource ending in overview.html. This is a common name for documentation which tend to get sprinkled all across dependencies. |
The duplicate finder plugin ignores the following classes by default unless the useDefaultClassIgnoreList flag is set to false.
| Regular expression | Description |
|---|---|
^.*\$/.* |

module-info |
JDK 9 module-info class. Plugin version 1.3.0+ |
^(.*\.)?.*\$.*$ |
matches Java inner and nested classes in any package. Plugin version 1.4.0+ |
^(.*\.)?package-info$ |
matches Java package-info class files in any package. Plugin version 1.4.0+ |
^(.*\.)?module-info$ |
matches Java module-info class files in any package. Plugin version 1.4.0+ |
The following local directory names will also always be ignored. Files in these directory are never checked or touched by the plugins:
| Regular expression | Description |
