如何使用 Gradle 任务运行两个不同的主类

Question

I am pretty new to gradle and unfamiliar with the Groovy language/build script syntax etc.

I have one main Class, which starts perfectly fine with

gradle run

But I now want to create a new Task (uitest), which should be called with something like:

gradle -q uitest

which should run like above, but with another mainClass.

My build script so far looks like this:

plugins {
id 'application'
id 'org.openjfx.javafxplugin' version '0.0.8'

}
mainClassName = 'streetsim.ui.StreetSimApp'

javafx {
    version = "11.0.2"
    modules = ['javafx.controls', 'javafx.fxml']
}

task uitest(type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath
    main = 'streetsim.ui.TemporaryUITestPool.main'
}

group 'groupname'
version '1.0-SNAPSHOT'


sourceCompatibility = 11

repositories {
    jcenter()
}

dependencies {
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.6.0'
}


test {
    useJUnitPlatform()
}

EDIT: I changed the task as following:

task uitest(type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath
    main = 'streetsim.ui.TemporaryUITestPool'
}

And now I get following error:

Error: JavaFX runtime components are missing, and are required to run this application

As mentioned in the comment to another answer below, I do not want to add VM arguments if possible as I do not want to require a local JavaFX installation

Answer 1

because this FX below are required you need to add the following to the java command (and remove.main as per comment above)

--add-modules javafx.controls,javafx.fxml --module-path <path_to_modules>
