I'm using the "flat" structure where the parent directory (cars_parent) is a sibling of its sub modules.
The parent's pom starts with <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> <packaging>pom</packaging> <artifactId>wmf-paper</artifactId> <groupId>edu.berkeley.ist.cars</groupId> <modules> <module>../cars_net</module> <module>../cars_download</module> <module>../cars_upload</module> </modules> In the pluginManagement section the section for the release plugin is as follows: <plugin> <artifactId>maven-release-plugin</artifactId> <groupId>org.apache.maven.plugins</groupId> <version>2.0-beta-7</version> <configuration> <tagBase>svn+ssh://[EMAIL PROTECTED]/svn/ist-svn/berkeley/projects/ist/as/webapps/cafe-paper-cars/tags</tagBase> </configuration> </plugin> Here's the tail of the output when it blows up. I don't understand what the problem is: [INFO] Working directory: /home/rusty/java/cars/cars_parent [INFO] Tagging release with the label wmf-paper-1.0.0...
