How to configure HTTP proxy settings during test execution?

Two options:

Manually configure the proxy 

<build>
  <plugins>
    <plugin>
      <groupId>org.eclipse.tycho</groupId>
      <artifactId>tycho-surefire-plugin</artifactId>
      <configuration>
        <argLine>-Dhttp.proxyHost=myproxy -Dhttp.proxyPort=1234</argLine>
      </configuration>
    </plugin>
  </plugins>
</build>

and disable the eclipse system proxy setting 

    if (Platform.isRunning() && getProxyService() != null
      && getProxyService().isSystemProxiesEnabled()
      && !getProxyService().hasSystemProxies()) {
      // XXX e3.5/gtk.x86_64 activate manual proxy configuration which
      // defaults to Java system properties if system proxy support is
      // not available
     getProxyService().setSystemProxiesEnabled(false);
     getProxyService().setProxiesEnabled(true);
    }

- or -

Make sure the native org.eclipse.core.net.* fragment for your platform is included in the test runtime so eclipse will pick up proxy settings configured on OS level: 

<build>
  <plugins>
    <plugin>
      <groupId>org.eclipse.tycho</groupId>
      <artifactId>tycho-surefire-plugin</artifactId>
      <configuration>
        <dependencies>
          <dependency>
            <type>p2-installable-unit</type>
            <artifactId>org.eclipse.core.net.[YOUR_PLATFORM]</artifactId>
            <version>[VERSION]</version>
          </dependency>
        </dependencies>
      </configuration>
    </plugin>
  </plugins>
</build>


How to use SWTBot or some UI tool for testing?

You need to configure the tycho-surefire-plugin to use the UI: 

<build>
  <plugins>
    <plugin>
      <groupId>org.eclipse.tycho</groupId>
      <artifactId>tycho-surefire-plugin</artifactId>
      <configuration>
        <useUIHarness>true</useUIHarness>
        <useUIThread>false</useUIThread>
      </configuration>
    </plugin>
  </plugins>
</build>

How to configure warning/error settings of the OSGi compiler?

To configure warnings: 

<plugin>
  <groupId>org.eclipse.tycho</groupId>
  <artifactId>tycho-compiler-plugin</artifactId>
  <version>${tycho-version}</version>
  <configuration>
    <compilerArgument>-warn:[+|-]warning_tokens_separated_by_comma</compilerArgument>
  </configuration>
</plugin>

The available warning tokens are listed in the Eclipse help. Same applies for the

-err

argument for configuring errors.

How to build plugin-based products with platform-specific fragments?

First you need to configure all os/ws/arch environments for which you want to build. Example POM snippet: 

<plugin>
  <groupId>org.eclipse.tycho</groupId>
  <artifactId>target-platform-configuration</artifactId>
  <version>${tycho-version}</version>
  <configuration>
  <resolver>p2</resolver>
    <environments>
      <environment>
        <os>win32</os>
        <ws>win32</ws>
        <arch>x86</arch>
      </environment>
      <environment>
        <os>win32</os>
        <ws>win32</ws>
        <arch>x86_64</arch>
      </environment>
    </environments>
  </configuration>
</plugin>

for plugin-based (as opposed to feature-based) .product files, tycho needs additional os/ws/arch attributes for the fragments in the .product file which are not required by PDE.

Example product file snippet: 

<plugin id="org.eclipse.swt.win32.win32.x86" fragment="true" os="win32" ws="win32" arch="x86"/>
<plugin id="org.eclipse.swt.win32.win32.x86_64" fragment="true" os="win32" ws="win32" arch="x86_64"/>

How to test OSGi declarative services?

You need to add bundle org.eclipse.equinox.ds to the test runtime: 


<plugin>
  <groupId>org.eclipse.tycho</groupId>
  <artifactId>tycho-surefire-plugin</artifactId>
  <configuration>
    <dependencies>
      <dependency>
        <type>p2-installable-unit</type>
        <artifactId>org.eclipse.equinox.ds</artifactId>
      </dependency>
    </dependencies>
  </configuration>
</plugin>

How do I include rootfiles?

Tycho provides partial support for PDE-style rootfiles. Rootfiles are associated and installed with a feature. See the TYCHO465RootFiles test for an example of using rootfiles.

A different approach is to use the maven-assembly-plugin to assemble a zip file. We do not have a worked example, but Kai Kreuzer documented his approach that was necessary prior to the introduction of rootfile support [1].
