Maven Notes

1. Frequent Repositories

(1) Maven Central

<repository><id>Maven Central</id><url>http://repo1.maven.org/maven2</url></repository>

(2) Activiti

<repository><id>Alfresco</id><name>Alfresco</name><url>http://maven.alfresco.com/nexus/content/groups/public</url></repository>

(3) Spring Release

<repository><id>spring-maven-release</id><name>Spring Maven Release Repository</name><url>http://maven.springframework.org/release</url></repository>

2. Install M2Eclipse Plugin on Eclipse 4.2 JUNO

url: http://m2eclipse.sonatype.org/sites/m2e

3. Import Existing Projects into Workspace and Enable Maven

4. While setting up Activiti in Action example code, Eclipse JUNO stuck when processing this:

 

Check the url, found this:

3.1.1 doesn't exist! How to handle this kind of problem?

I installed the jar in my local repository, no joy yet.

Solution: Nexus

(1) I installed Nexus locally, and start it.

(2) Upload activiti-spring 5.10, activiti-cxf 5.10, activiti-engine 5.10, mybatis 3.1.1 to Nexus's thirdparty repository.

(3)

5. Nexus

Command: nexus console

Default URL: http://localhost:8081/nexus

Default Account: admin, admin123

       <repository>                 <id>nexus</id>                 <url>http://127.0.0.1:8081/nexus/content/groups/public/</url>                 <releases>                    <enabled>true</enabled>                 </releases>                 <snapshots>                    <enabled>true</enabled>                 </snapshots>              </repository>

6. Nexus Uploading Problem:　does not allow updating artifacts.

Take it easy, this means you have already uploaded one identical jar, you can check the nexus's storage folder out.

7. Problem: The container 'Maven Dependencies' references non existing library

HERE IS THE KEY POINT:  tick off  'Resolve dependencies from Workspace projects'

Delev/Comtemplate: What's the underlying meaning of this option?
