在 Linux 上托管的 Sonatype Nexus 存储库上部署 Maven 工件

Question

I am new to Sonatype Nexus and Maven and trying examples as given in Maven by Example . I have a problem deploying artifacts generated by Maven to Nexus running on Linux. If my pom.xml has 'localhost:8081' as the repository, the deployment is a success. If I replace localhost with an IP address (10.193.4.5:8081) deployment fails with 'Access denied' error. Details below.

Error:
Downloading: h ttp://10.193.4.5:8081/nexus/content/repositories/snapshots/org/sonatype/mavenbook/simple/parent/0.8-SNAPSHOT/maven-metadata.xml

http://10.193.4.5:8081/nexus/content/repositories/snapshots/org/sonatype/mavenbook/simple/parent/0.8-SNAPSHOT/maven-metadata.xml

My configuration details are as follows.

1. Nexus (nexus-oss-webapp-1.9.1.1) installed on linux_x64 (RHEL5) as "root" user and running as service
2. Maven Apache Maven 3.0.3 (r1075438; 2011-02-28 23:01:09+0530) Maven home: /usr/local/apache-maven/apache-maven-3.0.3 Java version: 1.6.0_16, vendor: Sun Microsystems Inc. Java home: /usr/java1.6.0_16/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "2.6.18-8.el5", arch: "amd64", family: "unix"
3. settings.xml snapshots deployment deployment
4. pom.xml testing Internal Releases http://10.193.4.5:8081/nexus/content/repositories/snapshots</url>--> http://localhost:8081/nexus/content/repositories/snapshots

I guess this is related to a permission problem on Linux, and I am not able to debug.

1. What should be the ideal user for Nexus to run root or Nexus?
2. What should be the group and owner for a Sonatype-work folder?

Answer 1

Your problem is most likely related to networking and not to the Nexus setup. Try

nc -vz 10.193.4.5 8081

at the console to see if you can route packets to that address. To make it work with the IP, you'll probably need to add an /etc/hosts entry.
