maven - 使用Gradle找不到slf4j LoggerFactory类定义

Question

我正在尝试构建和运行在IntelliJ中使用slf4j登录的Spark网络服务器。它可以在最初用于添加日志记录的计算机上构建良好(在IntelliJ中也可以)，但不能在我的计算机上构建。

这是完整的build.gradle文件(有关使用记录器的部分，请参见project(':webserver'):

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "gradle.plugin.com.avast.gradle:docker-compose-gradle-plugin:0.3.27"
    }
}

subprojects {
    repositories {
        mavenLocal()
        mavenCentral()
        jcenter()
    }

    apply plugin: "java"
    apply plugin: "idea"
    apply plugin: "checkstyle"
    apply plugin: "pmd"
    apply plugin: "findbugs"
    apply plugin: "application"
    apply plugin: "com.avast.gradle.docker-compose"

    checkstyle {
        configFile = "../config/checkstyle/checkstyle.xml" as File
        toolVersion = "6.0"
    }
}

project(':webserver') {
    mainClassName = "org.passport.webserver.WebServer"
    dependencies {
        compile project(':core')
        compile "com.sparkjava:spark-core:2.6.0"
        testCompile 'junit:junit:4.12'
        compile group: 'org.json', name: 'json', version: '20090211'
        compile group: 'org.slf4j', name: 'slf4j-log4j12', version: '1.6.1'
    }

    sourceSets {
        main {
            java {
                srcDir 'src/main/java/'
            }
        }
    }
}

project(':customsUI') {
    mainClassName = "org.passport.customsui.CustomsUI"
    dependencies {
        compile project(':core')
        testCompile 'junit:junit:4.12'
    }

    sourceSets {
        main {
            java {
                srcDir 'src/main/java/'
            }
        }
    }
}

project(':handlerUI') {
    mainClassName = "org.passport.handlerui.HandlerUI"
    dependencies {
        compile project(':core')
        testCompile 'junit:junit:4.12'
    }

    sourceSets {
        main {
            java {
                srcDir 'src/main/java/'
            }
        }
    }
}

project(':core') {
    mainClassName = "org.passport.core.PassPortChaincode"
    dependencies {
        compile 'io.grpc:grpc-all:0.13.2'
        compile 'commons-cli:commons-cli:1.3.1'
        compile 'org.glassfish:javax.json:1.1.0-M1'
        compile files('lib/shim-client-1.0.jar')
        testCompile 'junit:junit:4.12'
    }

    sourceSets {
        main {
            java {
                srcDir 'src/main/java/'
            }
        }
    }
}

这是使用记录器的代码:

package org.passport.webserver;

import org.passport.webserver.endpoints.ContainerClaimDao;
import org.passport.webserver.endpoints.PackageClaimDao;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import static spark.Spark.before;
import static spark.Spark.get;
import static spark.Spark.path;
import static spark.Spark.post;

/**
 * The server matches requests (routs) and calls the appropriate endpoints.
 */
public final class Server {

    private static Logger logger = LoggerFactory.getLogger(Server.class);
    private static ContainerClaimDao containers = new ContainerClaimDao();
    private static PackageClaimDao packages = new PackageClaimDao();

    private Server() {

    }

    /**
     * Starts the router.
     * @param args run arguments
     */
    public static void main(String[] args) {
        path("/containers/:container-id", () -> {
            before("/*", (q, a) -> logger.info("Received api call: " + q.url() + "."));

            post("", (request, response) -> containers.add(request, response));

            get("/container-claims", (request, response) -> containers.get(request, response));

            get("/package-claims", (request, response) ->   packages.get(request, response));

        });
    }

}

这是我得到的错误:

我看过关于StackOverflow的几个问题，但似乎没有一个能解决问题:

java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory-我正在用gradle构建，不要认为我应该下载/在我的类路径中放入一些jar

ClassNotFoundException: org.slf4j.LoggerFactory-与上述

相同

NoClassDefFoundError: org/slf4j/Logger-再次 jar

Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory-我不确定“fat jars” / ShadowJar是否适用，也不确定如何修改构建文件以使用它们

NoClassDefFoundError: org/slf4j/LoggerFactory while creating a runnable *.jar with gradle-我已经尝试过几次刷新gradle，重新启动IntelliJ，甚至重新启动计算机

Gradle Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory-参见下文

我尝试了以下依赖项:

compile group: 'org.slf4j', name: 'slf4j-log4j12', version: '1.6.1'

compile 'org.slf4j:slf4j-api:1.7.24'和compile 'org.slf4j:slf4j-simple:1.7.24'

compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.6.1'

这些似乎都没有改变。有任何想法吗？

如果您使用Gradle，请将这两行添加到build.gradle依赖项中以使用Spark 2.6.0
compile "com.sparkjava:spark-core:2.6.0"compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.21'
