Maven failed to resolve dependencies - javax.activation

问题

I have a working maven web application which uses many jars. Trying to add javax.activation and do a mvn clean install fails.

I get "Failed to execute goal on project xxx: Could not resolve dependencies for project javax.activation:activation:jar:1.0.2 in central (http://build02.efollett.com:8081/artifactory/libs-release)

When I check my maven repository I see the activation jar there. For example, navigating to C:\Users\me.m2\repository\javax\activation\activation\1.0.2 I see the following.

activation-1.0.2.jar.lastUpdated
activation-1.0.2.pom
activation-1.0.2.pom.sha1
activation-1.0.2.pom.tmp.sha1.tmp

My colleague is using the same settings.xml and I have compared my local pom.xml to the version in cvs. They are all the same! Any thoughts on what I am missing?

Thanks for your help.

回答1:

The artifact you need is javax.activation:activation:jar:1.0.2 (pay attention to the jar part), while the artifact you have in your repo is javax.activation:activation:pom:1.0.2. Either place a jar one into your repo or add <classifier>pom</classifier> to your <dependency>.

Sun will not allow Maven to redistribute its binaries, including JavaMail JAR and Activation JAR. Instead, all users must install Sun binaries manually by downloading them from Sun's website and running the mvn install command.

1. Download Java Activation Framework

http://www.oracle.com/technetwork/java/javase/jaf-136260.html

and then

http://download.oracle.com/otn-pub/java/jaf/1.0.2-fcs/jaf-1_0_2-upd2.zip

2. Extract "jaf-1.0.2"

3. Run at folder "jaf-1.0.2"

mvn install:install-file -Dfile=activation.jar -DgroupId=javax.activation -DartifactId=activation -Dversion=1.0.2 -Dpackaging=jar

Add dependency to your pop.xml file

<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
