Deploying to New Internal Maven Repository

 原文  2016-07-16 15:51:53  2   1    java/ eclipse/ maven

Question

I have a completely empty file system set up as an internal Maven Repository. I am trying to deploy to this Repository via SFTP.

This is the first jar that I am deploying to the Repository and as I understand it is is possible to point it at a blank writable directory and maven will build up all the correct files.

When running the deploy target I get the following errors: 

[INFO] Downloading: scpexe://mvn.metcarob.com:7456/public/metcarob/com/BobDiary/BobDiary/0.0.1-SNAPSHOT/maven-metadata.xml

The gist of the error message is: File "/public/metcarob/com/BobDiary/BobDiary/0.0.1-SNAPSHOT/maven-metadata.xml" not found.

Of course this file isn't found. It is not in the repository as I am in the process of deploying it. I am expecting this process to create this file. As this is the first time the jar is being deployed to any repository the file can no possibly exist.

The distribution part of my POM is: 

  <distributionManagement>
    <repository>
      <id>ssh-repository</id>
            <name>ssh-repository</name>
      <url>scpexe://mvn.metcarob.com:71234/public</url>
    </repository>
  </distributionManagement>

Are there any settings/methods that I have missed?

(I am running maven via eclipse m2e)

UPDATE: Some extra information. In my POM I have 

  <!-- Enabling the use of SSH -->
  <extension>
    <groupId>org.apache.maven.wagon</groupId>
     <artifactId>wagon-ssh-external</artifactId>

     <version>2.10</version>
  </extension>

and my settings.xml is: 

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                          https://maven.apache.org/xsd/settings-1.0.0.xsd">
      <localRepository/>
      <interactiveMode/>
      <usePluginRegistry/>
      <offline/>
      <pluginGroups/>
      <servers>
          <server>
              <id>ssh-repository</id>
              <username>maven_repo</username>
              <configuration>
                  <sshExecutable>plink</sshExecutable>
                  <scpExecutable>sftp</scpExecutable>
                  <sshArgs></sshArgs>
                  <scpArgs>-o UserKnownHostsFile=/home/robert/.ssh/known_hosts</scpArgs>
              </configuration>
            <!-- <filePermissions>664</filePermissions>
            <directoryPermissions>775</directoryPermissions> -->
          </server>
      </servers>
      <mirrors/>
      <proxies/>
      <profiles/>
      <activeProfiles/>
</settings>

As far as I can see I have followed all the steps from http://maven.apache.org/plugins/maven-deploy-plugin/examples/deploy-ssh-external.html

It is possible to use a simple file system as a maven repository, no need to use a repository manager. I am using a amazon S3 and it works perfectly.

Additionally to the distributionManagement you have to declare a extension in maven, have a look at

deploy-ssh-external

One more thing :

In the stacktrace you are using 

scpexe://mvn.metcarob.com:7456

in the pom you use a different port 

scpexe://mvn.metcarob.com:71234

This might be a problem, also.
