Suggest not to set appsDirectory=apps when installing app in boost.

[patricktiu]

Since the LMP has a "smart" default for the appsDirectory, you might not need to set it yourself.

See the appsDirectory smart default documentation: https://github.com/OpenLiberty/ci.maven/blob/master/docs/deploy.md

boost.runtimes.openliberty.LibertyRuntime:

    /**
     * Invoke the liberty-maven-plugin to run the install-app goal.
     */
    private void installApp(String installAppPackagesVal) throws MojoExecutionException {

        Element deployPackages = element(name("deployPackages"), installAppPackagesVal);
        Element serverNameElement = element(name("serverName"), serverName);

        Xpp3Dom configuration = configuration(deployPackages, serverNameElement, getRuntimeArtifactElement());
        configuration.addChild(element(name("appsDirectory"), "apps").toDom());

        executeMojo(getPlugin(), goal("deploy"), configuration, env);
    }

There are other defaults specified as well that do not need to be...like this one:

element(name("outputDirectory"), "target/liberty-alt-output-dir"),

@cherylking We just put that back in last week since @chyt said it wasn't actually defaulted. Anyway, will save that for later since I have the Travis running in #389.

OK, I see the change. Will delete outputDirectory too..thx @cherylking

[patricktiu]

I can't remember but there is a reason to use a non-default outputDirectory for package goal.

Would that be running package goal with a running server?

[patricktiu]

I think @cherylking is right, the default outputDirect for package goal is target/liberty-alt-output-dir now in 3.0.1 and it is different from the one in run goal. So you don't need it.
