Using ${artifcactId}-Extention-Name in MANIFEST file can create invalid MANIFEST files --------------------------------------------------------------------------------------
Key: MJAR-102 URL: http://jira.codehaus.org/browse/MJAR-102 Project: Maven 2.x Jar Plugin Issue Type: Bug Affects Versions: 2.2, 2.1, 2.0 Environment: Java HotSpot(TM) Client VM (build 1.5.0_13-121) Reporter: Todd Caine If you have a maven dependency on an something with an artifactId that contains a '.' in it, it creates an illegal manifest file when trying to create an executable jar file (java -jar foo.jar). Exception in thread "main" java.io.IOException: invalid header field name: geronimo-jms_1.1_spec-Extension-Name at java.util.jar.Attributes.read(Attributes.java:409) at java.util.jar.Manifest.read(Manifest.java:167) at java.util.jar.Manifest.<init>(Manifest.java:52) at java.util.jar.JarFile.getManifestFromReference(JarFile.java:158) at java.util.jar.JarFile.getManifest(JarFile.java:145) Here's my configuration: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>my.class.Test</mainClass> <addClasspath>true</addClasspath> <addExtensions>true</addExtensions> <classpathPrefix>./lib/</classpathPrefix> </manifest> </archive> </configuration> </plugin> I added the following dependency: <dependency> <groupId>org.apache.geronimo.specs</groupId> <artifactId>geronimo-jms_1.1_spec</artifactId> </dependency> When the maven-archiver tries to create a manifest file with the JARs dependencies it adds the following to the META-INF/MANIFEST.MF file: geronimo-jms_1.1_spec-Extension-Name: geronimo-jms_1.1_spec geronimo-jms_1.1_spec-Implementation-Version: 1.0 After digging around a bit it turns out that '.' is an illegal character in the "Extension-Name" and "Implementaion-Version" header fields, which leads to the following exception when I try to run "java -jar Test.jar" java.io.IOException: invalid header field name: geronimo-jms_1.1_spec-Extension-Name -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
