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>

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?
