I am having an issue where the inclusion of a plugin using maven 2.0.9 works fine but in maven 2.1.0-RC3 it complains saying it can not find the plugin descriptor. I also saw the same behavior in RC2. I opened up the jar and see the plugin.xml file in META-INF/maven/plugin.xml. Here is the sample pom to illustrate the issue.
<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>com.test</groupId> <artifactId>resin-test</artifactId> <packaging>pom</packaging> <version>3.0.0</version> <name>resin test pom</name> <pluginRepositories> <pluginRepository> <id>caucho</id> <name>Caucho</name> <url>http://caucho.com/m2</url> </pluginRepository> </pluginRepositories> <build> <plugins> <plugin> <groupId>com.caucho</groupId> <artifactId>resin-maven-plugin</artifactId> <version>3.1.6</version> </plugin> </plugins> </build> </project> And here is the error I get when trying to install it CWD:~/temp/testpom chandy: mvn -version Apache Maven 2.1.0-RC3 (r754932; 2009-03-16 12:31:06-0400) Java version: 1.6.0_05 Java home: /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home Default locale: en_US, platform encoding: MacRoman OS name: "mac os x" version: "10.5.4" arch: "x86_64" Family: "mac" CWD:~/temp/testpom chandy: mvn install -X + Error stacktraces are turned on.
