I'm trying to eliminate commons-logging from being transitively passed on to projects that depend on my library and my library uses spring. Spring uses commons-logging but doesn't mark it as optional or scope:provided, however when I try to exclude commons logging from a spring dependency, I no longer get it even though it is declared in my pom.
Here's a simple pom which exposes the problem (maven 2.0.4): <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>some.groupid</groupId> <artifactId>blah</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>blah</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1</version> <scope>provided</scope> <exclusions> <exclusion> <groupId>avalon-framework</groupId> <artifactId>avalon-framework</artifactId> </exclusion> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> <exclusion> <groupId>log4j</groupId> <artifactId>log4j</artifactId> </exclusion> <exclusion> <groupId>logkit</groupId> <artifactId>logkit</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-dao</artifactId> <version>2.0</version> <exclusions> <exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> </exclusions> </dependency> </dependencies> </project> Now if you remove the commons-logging exclusion from the spring-dao dependency, commons-logging get correctly pulled down. Also note that this problem does NOT surface if I use spring-context even though the poms appear to be practically identical.
