#1571 Dependency collisions

[Andrew Pennebaker]

I use htmlunit and jetty, but htmlunit's jetty version conflicts with my own. In my project, I substitute httpclient instead:

<dependency>
  <groupId>net.sourceforge.htmlunit</groupId>
  <artifactId>htmlunit</artifactId>
  <version>2.13</version>
  <exclusions>
    <exclusion>
      <groupId>org.eclipse.jetty</groupId>
      <artifactId>jetty-websocket</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<!-- Fix htmlunit dependency error -->
<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3.1</version>
</dependency>

In the future, could htmlunit use the httpclient package instead of jetty-websocket? Then htmlunit would integrate more easily with other projects.

[Andrew Pennebaker]

Crap, turns out it's not a substitution. Whether or not I exclude jetty-websocket, htmlunit still lacks the needed httpclient package. Could we please fix htmlunit's pom to include this?

[Ahmed Ashour]

I am not sure I understand the issue.

jetty and httpclient are two different packages, and they shouldn't conflict with each other.

What error you get, and what code you use that shows that conflict.

[Andrew Pennebaker]

I misspoke. It's not that the two packages collide with one another, it's
that httpclient appears to be a necessary package when using htmlunit's
WebClient. If I remove httpclient as a dependency for my htmlunit user
code, Maven complains of missing network classes.

HttpClient is mandatory for HtmlUnit to work, and it is currently updated to latest 4.3.2 version, and is not meant to be used with with previous 4.2.x

I am not sure why you directly use HttpClient classes, but you need to upgrade your code accordingly.

[Andrew Pennebaker]

I don't use HttpClient directly. I use htmlunit's WebClient class, which
needs HttpClient to work. (However, htmlunit's pom fails to include this
dependency.)

I believe you have a mis-configured environment/pom.

Please send your complete project, so we can see your error.

[Andrew Pennebaker]

Error details:

If I try to use htmlunit's WebClient, mvn compile complains of missing
SchemeSocket classes.

Mitigation:

By manually adding an httpclient dependency, the compile error goes away.

pom.xml:

...
      <dependencies>
        <dependency>
          <groupId>net.sourceforge.htmlunit</groupId>
          <artifactId>htmlunit</artifactId>
          <version>2.13</version>
          <exclusions>
            <exclusion>
              <groupId>org.eclipse.jetty</groupId>
              <artifactId>jetty-websocket</artifactId>
            </exclusion>
            <exclusion>
              <groupId>org.eclipse.jetty.orbit</groupId>
              <artifactId>javax.servlet</artifactId>
            </exclusion>
          </exclusions>
        </dependency>
        <!-- Fix htmlunit dependency error -->
        <dependency>
          <groupId>org.apache.httpcomponents</groupId>
          <artifactId>httpclient</artifactId>
          <version>4.3.1</version>
        </dependency>
        <dependency>
          <groupId>org.eclipse.jetty.aggregate</groupId>
          <artifactId>jetty-all</artifactId>
          <version>${jetty.version}</version>
          <scope>test</scope>
        </dependency>
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>4.11</version>
          <scope>test</scope>
        </dependency>
      </dependencies>
...

I politely request that httpclient be included in htmlunit's own pom.xml,
to fix the dependency issue.

[Ahmed Ashour]

HtmlUnit 2.13 pom.xml already includes httpclient 4.3.1, you can check :)

Please provide the jetty version you use, and what is the full class name of "SchemeSocket classes"

[Andrew Pennebaker]

No problem!

<jetty.version>7.6.14.v20131031</jetty.version>

org.apache.http.conn.scheme.Scheme

attached is a project, 'mvn clean compile' works.

Andrew, any news? Can we close this?

[RBRi]

No response, will close this.
