Maven site deploy issue

Question

I am using the maven site-deploy command. I am using maven 2.2.1 with jdk 6.

I get the following error:

org.apache.maven.lifecycle.LifecycleExecutionException: Wagon protocol '' doesn't support directory copying
    at org.apache.maven.lifecycle.DefaultLifecycleExecutor.executeGoals(DefaultLifecycleExecutor.java:719)

The pom.xml has the following distribution Management section:

    <site>
        <id>app123</id>
        <url>/app/il3/apache-tomcat-7.0.57/webapps/build/app123</url>
    </site>

Please advise.

Thanks, B

Apart from that i would recommend to upgrade http://maven.apache.org/maven-2.x-eol.html — khmarbaise, Dec 22 '14 at 13:45

I'm pretty sure you're just having trouble to configure your maven <site> tag. at the URL from the official documentation it states:

url: This is the core of the repository element. It specifies both the location and the transport protocol to be used to transfer a built artifact (and POM file, and checksum data) to the repository.

And you're missing your transport protocol on your URL. Therefore the

Wagon protocol '' doesn't support directory copying

Here is the list of supported protocols, from their site:

File
HTTP
HTTP lightweight
FTP
SSH/SCP
WebDAV

So why don't you try specifying a valid URL? <url>file://var/<url> Here are some more examples and a explanation

That worked! Thanks. I should have spotted that :-). – user518066 Dec 22 '14 at 13:44 — user518066, Dec 22 '14 at 13:44

I've got a similar problem but for protocol http Wagon protocol 'http' doesn't support directory copying on a nexus site.

I solved it by switching to dav protocol. It needs to be added as extension.

<project>
   ...
   <distributionManagement>
      <site>
        <id>uumds-site-repository</id>
        <name>Uumds Site Repository</name>
        <!--
        <url>http://vs-b1-repo1:8081/nexus/content/sites/uumds/${project.groupId}-${project.artifactId}-${project.version}</url>
        -->
        <url>dav:http://vs-b1-repo1:8081/nexus/content/sites/uumds/${project.groupId}-${project.artifactId}-${project.version}</url>
      </site>
  </distributionManagement>
  ...
  <build>
    <extensions>
        <extension>
            <groupId>org.apache.maven.wagon</groupId>
            <artifactId>wagon-webdav-jackrabbit</artifactId>
            <version>2.10</version>
        </extension>
    </extensions>
  ...
  </build>
</project>
