Question

Extreme edit to question to have it make more sense:

Let’s assume that I need to use a local version of httpclient rather than one that I can just pull from an online repo (due to signing reasons). The way that I want to handle this is like so…

ivy.xml

---

<dependencies>  
    ...Other dependencies here
    <dependency org="com.apache" name="httpclient" rev="4.2.2" conf="compile->default" ext="jar" />
</dependencies>

---

ivysettings.xml

---

<settings defaultResolver="central"/>

<resolvers>
<url name="repo">
    <ivy pattern="http://myServer:8080/Repo/[organisation]/[artifact]/[revision]/ivy.xml" />
    <artifact pattern="http://myServer:8080/Repo/[organisation]/[artifact]/[revision]/[artifact].[ext]"/>
</url>

<url name="httpclient">
    <artifact pattern="http://myServer:8080/Repo/com.apache/httpclient/4.2.2/[artifact].[ext]"/>
</url>



<modules>
    <module organisation="com.apache" resolver="repo" />
    <module organisation="com.httpclient" resolver="httpclient" />
</modules>

---

Now what I’m hoping for here (and haven’t been having much luck with) is the com.apache resolver looking for myServer:8080/Repo/com.apache/httpclient/4.2.2/ivy.xml and reading that, here’s the contents of that file:

ivy.xml (in myServer:8080/repo/… directory)

---

    <dependency org="com.httpclient" name="commons-codec" rev="1.6" />
    <dependency org="com.httpclient" name="commons-logging" rev="1.1.1" />
    <dependency org="com.httpclient" name="fluent-hc" rev="4.2.2" />
    <dependency org="com.httpclient" name="httpclient" rev="4.2.2" />
    <dependency org="com.httpclient" name="httpclient-cache" rev="4.2.2" />
    <dependency org="com.httpclient" name="httpcore" rev="4.2.2" />
    <dependency org="com.httpclient" name="httpmime" rev="4.2.2"/>

---

The reasoning behind wanting to read the second xml file rather than including the markup in my first file is pretty obvious when you consider how many LOC that would add to something that we include frequently. It also makes all future includes easier as well.

Right now the error that I’m getting is:

Some projects fail to be resolved
Impossible to resolve dependencies of com.myCompany#myProgramt;working@CompName
unresolved dependency: com.apache#httpclient;4.2.2: not found

Thanks for your help on this matter.

Answer 1

Ivy expects to find all the dependencies of a given artifact in the same resolver. So, it finds the artifacts for com.apache in your repo resolver, and expects to find com.httpclient in there as well.

Ivy also will roll through your <ivy pattern.../> and <artifact pattern.../> statements in order within the same resolver declaration. You can use this to your advantage to create a single resolver which hits both repositories in the order you want:

<url name="amalgamation">
    <ivy pattern="http://myServer:8080/Repo/[organisation]/[artifact]/[revision]/ivy.xml" />
    <artifact pattern="http://myServer:8080/Repo/[organisation]/[artifact]/[revision]/[artifact].[ext]"/>
    <artifact pattern="http://myServer:8080/Repo/com.apache/httpclient/4.2.2/[artifact].[ext]"/>
</url>
