I tried JAX-RS and made a note of the procedure

environment

I will omit the installation.

procedure

--Create a gradle project In Eclipse, create a new project by selecting [New]> [Gradle]> [Gradle Project].

--Open the project properties and add "Project Facets".

--Add "Dynamic WEB module". At that time, select "Runtime" on the right side of the project facet screen and select "Glassfish 4".

--Modify build.gradle as follows.

build.gradle

apply plugin: 'war'
apply plugin: 'java-library'

repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    providedCompile 'org.projectlombok:lombok:1.16.4'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.8.6'
    compile 'com.fasterxml.jackson.jaxrs:jackson-jaxrs-json-provider:2.8.6'
	providedCompile 'javax:javaee-web-api:7.0'
	providedCompile fileTree(dir: '/glassfish4/glassfish/modules', include: '*.jar')

    api 'org.apache.commons:commons-math3:3.6.1'
    implementation 'com.google.guava:guava:21.0'
    testImplementation 'junit:junit:4.12'
}

war {
    exclude 'WEB-INF/lib/**'
    exclude 'WEB-INF/classes/**'
}

--Right-click on the project and select [Gradle]> [Refresh Gradle Project].
At this time, there is a mysterious event that the runtime of Glassfish in the library disappears. I need to open the project phi set again and reattach it ... I don't know why (sweat)

--After that, write the source file, add it to the server, and execute it.
