Gradle不知道Java语法错误吗？

Question

When I run my "build" Gradle task it is downloading all my dependencies as expected, however it does not seem to pick up on the fact that I have a Java Syntax error.

I have purposely created a syntax error with a missing ; to check this.

Why is this happening and how can I solve this?

Java class:

package client;

import org.hibernate.Session;

import util.HibernateUtil;
import entity.Message;


public class HelloWorldClient {
    public static void main(String[] args) {

                Session session = HibernateUtil.getSessionFactory().openSession();
                session.beginTransaction();

                Message message = new Message( "Hello World with Hibernate & JPA Annotations" ) //note no ;

                session.save(message);

                session.getTransaction().commit();
                session.close();

    }
}

Build.gradle:

group 'test'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'application'

mainClassName = "src.client.HelloWorldClient"

repositories {
    mavenCentral()
}

dependencies {
    compile 'mysql:mysql-connector-java:5.1.38'
    compile 'antlr:antlr:2.7.7'
    compile 'dom4j:dom4j:1.6.1'
    compile 'org.hibernate.common:hibernate-commons-annotations:4.0.4.Final'
    compile 'org.hibernate:hibernate-core:4.3.5.Final'
    compile 'org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.0.Final'
    compile 'org.jboss:jandex:1.1.0.Final'
    compile 'org.javassist:javassist:3.18.1-GA'
    compile 'org.jboss.logging:jboss-logging:3.1.3.GA'
    compile 'org.jboss.logging:jboss-logging-annotations:1.2.0.Beta1'
    compile 'org.jboss.spec.javax.transaction:jboss-transaction-api_1.2_spec:1.0.0.Final'
}

Answer 1

You don't have any source files under src/main/java . Move the client, domain, entity packages under there and you'll get your compile error :)

Answer 2

Skipping task ':compileJava' as it has no source files.

Move your sources to src/main/java or adjust your build file.
