我无法使用Gradle、Dropwizard和IntelliJ调试JavaEE应用程序

我有一个带有Gradle的JavaEE应用程序，我在官方文档（针对Maven）和Gradle的另一个指南之后添加了Dropwizard：



该应用程序配置良好，并使用Gradle和Dropwizard运行，但我想使用断点调试该应用程序，但我无法这样做。我遵循以下指南：







它看起来正常，因为当我运行命令时：

sudo./gradlew run-Dorg.gradle.debug=true——没有守护进程

Gradle等待我在IntelliJ中单击远程调试配置（我创建了它）来运行应用程序，这样它应该是正常的。然而，它从未停止在我的断点（看起来它忽略了它们）。有什么想法吗？

我分享我认为重要的文件：



build.gradle:

apply plugin: 'com.google.protobuf'
apply plugin: 'maven'
apply plugin: 'maven-publish'
apply plugin: 'application'
apply plugin: 'com.github.johnrengelman.shadow'

project.ext {
    dropwizardVersion = '1.3.0'
    configPath = "$rootProject.projectDir/config/"
}

//
// Loads of repositories and dependencies including dropwizard
//

protobuf {
// Configure the protoc executable
    protoc {
        // Download from repositories
        artifact = 'com.google.protobuf:protoc:3.0.0'
    }

    generateProtoTasks.generatedFilesBaseDir = 'generated'

    generateProtoTasks {
        // all() returns the collection of all protoc tasks
        all().each { task ->
            // Here you can configure the task
        }

        // In addition to all(), you may get the task collection by various
        // criteria:

        // (Java only) returns tasks for a sourceSet
        ofSourceSet('main')

    }
}

mainClassName = "com.company.MyApplication"

run {
    args 'server', configPath + ‘myapplication_config.yml'
}

shadowJar {
    mergeServiceFiles()
    exclude 'META-INF/*.DSA'
    exclude 'META-INF/*.RSA'
}

jar {
    manifest {
        attributes 'Main-Class': mainClassName
    }
}

build.dependsOn shadowJar

public class MyApplicationConfiguration extends Configuration {

}

MyApplicationApplication（Dropwizard应用程序）：



public class MyApplicationApplication extends Application<MyApplicationConfiguration> {

    public static void main(String[] args) throws Exception {

        new MyApplicationApplication().run(args);
    }

    @Override
    public void run(MyApplicationConfiguration configuration,
                    Environment environment) {

        environment.jersey().register(new RESTUserBilling());

    }
}

myapplication\u config.yml:

apply plugin: 'com.google.protobuf'
apply plugin: 'maven'
apply plugin: 'maven-publish'
apply plugin: 'application'
apply plugin: 'com.github.johnrengelman.shadow'

project.ext {
    dropwizardVersion = '1.3.0'
    configPath = "$rootProject.projectDir/config/"
}

//
// Loads of repositories and dependencies including dropwizard
//

protobuf {
// Configure the protoc executable
    protoc {
        // Download from repositories
        artifact = 'com.google.protobuf:protoc:3.0.0'
    }

    generateProtoTasks.generatedFilesBaseDir = 'generated'

    generateProtoTasks {
        // all() returns the collection of all protoc tasks
        all().each { task ->
            // Here you can configure the task
        }

        // In addition to all(), you may get the task collection by various
        // criteria:

        // (Java only) returns tasks for a sourceSet
        ofSourceSet('main')

    }
}

mainClassName = "com.company.MyApplication"

run {
    args 'server', configPath + ‘myapplication_config.yml'
}

shadowJar {
    mergeServiceFiles()
    exclude 'META-INF/*.DSA'
    exclude 'META-INF/*.RSA'
}

jar {
    manifest {
        attributes 'Main-Class': mainClassName
    }
}

build.dependsOn shadowJar

IntelliJ IntelliJ 2018.2.1（社区版）中的远程配置

格拉德尔2.12

Java版本1.8.0_181

Dropwizard版本1.3.0

通过使用

-Dorg.gradle.debug=true

，您正在调试gradle的流程，而不是正在处理的应用程序。Gradle在不同的进程中运行应用程序。您应该尝试

gradle--debug jvm run

。阅读更多关于这个和

和Gradle，说真的。2.12太老了。使用

如果2.12不理解调试jvm（可能是这样），那么只需找到一种方法，向应用程序运行的jvm（而不是Gradle本身）提供如下字符串-

-agentlib:jdwp=transport=dt_socket，server=y，suspend=n，address=5005

。

谢谢，它可以工作。Gradle2.12理解——调试jvm。不过，我会听从你的建议，并尝试更新Gradle。
