Hi Brett,
Thanks for the quick response.
Do you have an Issue Tracker number so I can follow-up on this?
Thanks,
Jane

This seems to be a bug in Maven with the way the version ranges are
being handled. You can work around it by declaring the JSP API
dependency directly in your POM.

Hi Maven Gurus,
I'm really puzzled... Can someone in the forum explain this to me?
I have a simple pom.xml that defines the a dependency on jsp-impl
from the Maven repository: http://download.java.net/maven/2
--------------------------pom.xml-----------------------------
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0";

Running "mvn install" will fail with the message:
Downloading:
http://repo1.maven.org/maven2/javax/servlet/jsp/jsp-api/2.1.3-b05/jsp-api-2.1.3-b05.jar
[INFO]

[INFO] Failed to resolve artifact.
Missing:
----------
1) javax.servlet.jsp:jsp-api:jar:2.1.3-b05
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=javax.servlet.jsp
-DartifactId=jsp-api -Dversion=2.1.3-b05 -Dpackaging=jar
-Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the
file there:
mvn deploy:deploy-file -DgroupId=javax.servlet.jsp
-DartifactId=jsp-api -Dversion=2.1.3-b05 -Dpackaging=jar
-Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
Path to dependency:
1) maven.test:simple:jar:1.0
2) org.glassfish.web:jsp-impl:jar:2.1.3-b17
3) javax.servlet.jsp:jsp-api:jar:2.1.3-b05
----------
1 required artifact is missing.
for artifact:
maven.test:simple:jar:1.0
from the specified remote repositories:
central (http://repo1.maven.org/maven2),
java.net (http://download.java.net/maven/2)
It's complaining about resolving the artifact jsp-api. But this
artifact (javax.servlet.jsp:jsp-api:jar:2.1.3-b05) exists in java.net
(http://download.java.net/maven/2/javax/servlet/jsp/jsp-api/2.1.3-b05/).
Looks like it's trying to download the artifact from the Central repo
(http://repo1.maven.org/maven2) and not even search for it in
java.net. The message at the end is not true.
If I explicitly define jsp-api artifact in the pom.xml then it
compiles successfully.
Is this a bug in Maven? a known issue?
I'm using Maven version 2.2.1 and JDK version 1.6.
Thanks,
Jane
