                            <!-- Skip requirejs optimization if true -->

build-config.js looks like

({
    appDir: "${basedir}/src/main/webapp",
    baseUrl: "js",
    dir: "../../target/build",

    optimizeCss: "standard.keepLines",
    mainConfigFile: "../../src/main/webapp/js/main.js",

    inlineText: true,
    removeCombined: true,
    fileExclusionRegExp: /^build/,

    modules: [
    {
        name: "main"
    }
    ]
})

The war-exclusion works fine, but the target/build is not included in the war built.

mvn package -Poptimize fails.
