Connection Timeout Issue

[MatthewEdge]

When running Scoverage on a Jenkins build node at work, the build constantly fails on a Connection timed out error.

My scoverage Maven entry looks like the following:

        <plugin>
            <groupId>org.scoverage</groupId>
            <artifactId>scoverage-maven-plugin</artifactId>
            <version>1.1.1</version>
            <configuration>
                <scalaVersion>2.10.4</scalaVersion>
                <aggregate>true</aggregate>
                <highlighting>true</highlighting>
            </configuration>
            <executions>
                <execution>
                    <id>packageReport</id>
                    <phase>package</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

For reference, here is the error I see when running maven with -X. Any ideas?

[MatthewEdge]

Please let me know if any further information is needed. Thanks!

[gslowikowski]

Dtd file referenced by 'cobertura.xml' cannot be loaded for some reason.

[MatthewEdge]

Is it correct to say this DTD file is a network resource?

[gslowikowski]

There is a problem with reading DTD file referenced by cobertura.xml file.

<!DOCTYPE coverage SYSTEM "https://raw.githubusercontent.com/cobertura/cobertura/master/cobertura/src/site/htdocs/xml/coverage-04.dtd">

I have different error when working offline:
java.net.UnknownHostException: raw.githubusercontent.com
and this is reasonable. Why you have connection timeout, I don't know.

I will try to disable dtd resolving when opening cobertura.xml

[gslowikowski]

Can you try 1.2.0-SNAPSHOT version of the plugin?

You will have to add:

            <repositories>
                <repository>
                    <id>sonatype-nexus-snapshots</id>
                    <name>Sonatype Nexus Snapshots</name>
                    <url>https://oss.sonatype.org/content/repositories/snapshots</url>
                    <releases>
                        <enabled>false</enabled>
                    </releases>
                    <snapshots>
                        <enabled>true</enabled>
                    </snapshots>
                </repository>
            </repositories>

            <pluginRepositories>
                <pluginRepository>
                    <id>sonatype-nexus-snapshots</id>
                    <name>Sonatype Nexus Snapshots</name>
                    <url>https://oss.sonatype.org/content/repositories/snapshots</url>
                    <releases>
                        <enabled>false</enabled>
                    </releases>
                    <snapshots>
                        <enabled>true</enabled>
                    </snapshots>
                </pluginRepository>
            </pluginRepositories>

to your pom.xml file.

[gslowikowski]

@MatthewEdge, did you try 1.2.0-SNAPSHOT? Can this issue be closed?

[MatthewEdge]

So sorry for the delay! (Busy busy at work)

I will try this fix today. Thanks!

hi!
we're encountering a strange error with the plugin.

-we're behind a webproxy; we've set the proxy value in the settings.xml
-version using: 1.2.0-SNAPSHOT, with the aforementioned repository entries in the pom.xml.

StackTrace goes as follows:

[ERROR] Server returned HTTP response code: 407 for URL: http://cobertura.sourceforge.net/xml/coverage-04.dtd
java.io.IOException: Server returned HTTP response code: 407 for URL: http://cobertura.sourceforge.net/xml/coverage-04.dtd

Any ideas?

[gslowikowski]

New 1.2.0-SNAPSHOT snapshot deployed, documentation site updated.

Try it, please.

[gslowikowski]

Nobody complains, so I assume, it's fixed.

[MatthewEdge]

Apologies for the slow replies. Issue was fixed. Thanks!

[ChengGit]

Hi, could you release that snapshot version? I am behind a proxy, so I could only use code that's in central maven repo..
