Error when building fragment with Tycho: "xyz.fragment cannot be installed in this environment because its filter is not applicable"

While running mvn install on a fragment project in Eclipse I got this error:

${fragment name} cannot be installed in this environment because its filter is not applicable.

Using Eclipse-PlatformFilter: (osgi.os=macosx) in the Manifest breaks the build.

Here's the output surrounding the key error (IDs/directory names redacted):

[INFO] Resolving dependencies of MavenProject: ${fragmentID}:4.3.0-SNAPSHOT @ ${fragmentDir}/pom.xml
[INFO] {osgi.os=linux, org.eclipse.update.install.features=true, osgi.arch=x86_64, osgi.ws=gtk}
[ERROR] Cannot resolve project dependencies:
[ERROR]   Problems resolving provisioning plan.:
[ERROR]      ${fragment name} cannot be installed in this environment because its filter is not applicable.
[ERROR] 
[ERROR] See http://wiki.eclipse.org/Tycho/Dependency_Resolution_Troubleshooting for help.

The link (http://wiki.eclipse.org/Tycho/Dependency_Resolution_Troubleshooting) doesn't help.

I found a few similar errors on the internet (component X cannot be installed in this environment because its filter is not applicable), but they all apply to instances where it's downloaded software and there's either no solution or the solution isn't applicable to my case.

Grateful for any help!

Edit: I found that using Eclipse-PlatformFilter: (osgi.os=macosx) in the host plugin works, and also Eclipse-PlatformFilter: (| (osgi.os=macosx) (osgi.os=linux) (osgi.os=win32) ) in the fragment works. It seems that the build goes through each environment set in an ancestor pom, and it breaks when the fragment doesn't apply for any one of those environments.... surely there's some flag I could set to prevent that?

Tycho builds for all the operating system environments configured through the POM. There is currently no way to automatically filter these environments to what is configured as Eclipse-PlatformFilter. So when building a fragment only for a certain operating system, you need to manually override the <environments> configuration from your parent POM in the POM of the fragment:

<build>
    <plugins>
        <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>target-platform-configuration</artifactId>
            <version>${tycho-version}</version>
            <configuration>
                <environments>
                    <environment>
                        <os>macosx</os>
                        <ws>cocoa</ws>
                        <arch>x86_64</arch>
                    </environment>
                </environments>
            </configuration>
        </plugin>
    </plugins>
</build>
