findbugs-slf4j

findbugs-slf4j copied to clipboard

Hi, I'm using Gradle 5.2.1 and Java 11 in Windows 10.

I'd tried to run the following build.gradle file, which also tells what exactly other dependencies I'm using:

plugins {
    id "com.github.spotbugs" version "1.6.11"
    id "java-library"
}

ext.versionFbContrib = "7.4.3.sb"
ext.versionFindBugsSlf4j = "1.4.2"
ext.versionFindSecBugs = "1.8.0"
ext.versionJcip = "1.0"
ext.versionSlf4j = "1.8.0-beta4"
ext.versionSpotBugs = "3.1.12"

dependencies {
    compile group: 'org.slf4j', name: 'slf4j-api', version: versionSlf4j
    spotbugs configurations.spotbugsPlugins.dependencies
    api group: 'net.jcip', name: 'jcip-annotations', version: versionJcip
    api group: 'com.github.spotbugs', name: 'spotbugs-annotations', version: versionSpotBugs
    spotbugsPlugins group: 'com.h3xstream.findsecbugs', name: 'findsecbugs-plugin', version: versionFindSecBugs
    spotbugsPlugins group: 'com.mebigfatguy.fb-contrib', name: 'fb-contrib', version: versionFbContrib
    spotbugsPlugins group: 'jp.skypencil.findbugs.slf4j', name: 'bug-pattern', version: versionFindBugsSlf4j
}

println "Using Java " + org.gradle.api.JavaVersion.current() + "."

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

spotbugs {
    toolVersion = versionSpotBugs
    effort = "max"
    reportLevel = "low"
}

tasks.withType(com.github.spotbugs.SpotBugsTask) {
    pluginClasspath = project.configurations.spotbugsPlugins
    reports {
        xml.enabled = false
        html.enabled = true
    }
}

spotbugsTest.enabled = false

Further, I have a HelloWorld.java in the src\main\java\com\example folder. This is its contents:

package com.example;

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello World");
    }
}

Running it with gradle clean build --stacktrace produces this output:

> Configure project :

SLF4J: No SLF4J providers were found.

If I remove or comment-out the spotbugsPlugins group: 'jp.skypencil.findbugs.slf4j', name: 'bug-pattern', version: versionFindBugsSlf4j line from the build.gradle file, it compiles nicely. This shows up that the findbugs-slf4j plugin is probably the culprit. Note that I'm also using other SpotBugs plugins and they are fine.
