Is it possible to force Karma to use a local node install, instead of the globally installed node?

[xavierhaurie]

See the following: https://github.com/karma-runner/karma/issues/1975

I would like to achieve the same thing from the maven-karma-plugin

Thanks!

The following is working fine on a project i have here:

<configuration>
  ...
   <karmaExecutable>SOME/WHERE/node.exe SOME/WHERE/ELSE/node_modules/karma/bin/karma</karmaExecutable>
  ...
</configuration>

@asa-git Thank you. I tried that but no cigar.

pom.xml:

<plugin>
                <groupId>com.kelveden</groupId>
                <artifactId>maven-karma-plugin</artifactId>
                <version>1.6</version>
                <executions>
                    <execution>
                    <phase>test</phase>
                    <goals>
                        <goal>start</goal>
                    </goals>
                    </execution>
                </executions>
                <configuration>
                    <!-- this configuration emulates running this on the command line: -->
                    <!--./target/node/node ./node_modules/.bin/karma start karma.conf.for.maven.build.js-->
                    <karmaExecutable>${basedir}/target/node/node ${basedir}/node_modules/.bin/karma</karmaExecutable>
                    <!--<karmaExecutable>target/node/node node_modules/.bin/karma</karmaExecutable>-->
                    <configFile>karma.conf.for.maven.build.js</configFile>
                </configuration>
            </plugin>

when running mvn install I get the following output:

I am stumped.

[asa-git]

here is an extract from the pom I updated to test your issue (I'm on windows)

<configuration>
        <karmaExecutable>C:/apps/nodejs/4.2.x64/node.exe ${basedir}/node_modules/karma/bin/karma</karmaExecutable>        
        <configFile>src/test/resources/conf/karma.conf.js</configFile>
</configuration>

Note that I'm not referring to the karma script in the node_modules/.bin but the one directly present in karma: node_modules/karma/bin/karma

Also, the generation of the path to execute is handled here: https://github.com/karma-runner/maven-karma-plugin/blob/master/src/main/java/com/kelveden/karma/KarmaUtils.java#L76 You might have to refer to node with the absolute path (directly or via the maven basedir placeholder as seen in the example above)

Hopefully that will fix your issue in your mac env.

It seems to be a problem from Unix with ProcessBuilder : http://stackoverflow.com/questions/33000007/processbuilder-no-such-file-or-directory-but-runtime-exec-works

On windows, no problems, but on linux This do not works, because a whitespace is present <karmaExecutable>${basedir}/target/node/node ${basedir}/node_modules/.bin/karma</karmaExecutable> And this works, since no whitespace is present <karmaExecutable>${basedir}/target/node/node node_modules/.bin/karma</karmaExecutable>

So for now on linux, using a local karma is possible, but not using a local node and a local karma

If we want it to work, osAgnosticPathToExe should be split before given to the ProcessBuilder https://github.com/karma-runner/maven-karma-plugin/blob/master/src/main/java/com/kelveden/karma/KarmaUtils.java#L84

@kelveden Any updates on this?

[kelveden]

Sorry folks, I'd almost forgotten that this project even existed. It has been years since I even used it let alone looked at the code. I barely use maven these days. So I'm not in a good position to comment on the above, sorry. I'd suggest either forking and fixing. Alternatively, something I should have done years ago was to hand over control of this project to someone with more use for it - assuming that there is still the interest in it. If that's anyone here then let me know. Have added a notice to the README explaining as much.

[silk-bahamut]

I have post a pull request with the correction I am using locally. The only thing missing is merging and releasing to central maven

If you want to find about it : https://github.com/silk-bahamut/maven-karma-plugin

[asa-git]

If @silk-bahamut wants to take over, seems fair as he has a PR pending. If he can't or doesn't want to, I can I suppose. This plugin has very little need of maintenance anyway. Best regards.

[moose-byte]

To anyone that is still using this plugin and has this problem, I recommend the frontend-maven-plugin. You can replace this functionality and choose the node/npm runtime to execute with.
