SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder"

[ati90ati]

Hello,

I have detected a problem in the plugin after upgraded to a newer version from 1.6.9.

Task :spotbugsMain
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

This problem occurs in the version 1.6.10 / 1.6.11 / 1.7.0.
It happens on Java 8 and Java 11 also.
Gradle used: 5.2.1
As I observed it happens only if I have a project with Spring Boot (so this error will be present in each project which uses Spring Boot).
NOTE: Even the latest version of Spring Boot uses 1.7.x for the slf4j-api dependency.

Maybe this problem occurred after upgrading to slf4j-api version 1.8.0-beta-x

I've created a sample project to reproduce the problem:
https://github.com/ati90ati/bugreport-spotbugs-gradle-plugin-logging
You can run it with this command: ./gradlew clean build -PenableSpotbugs --warning-mode all

I hope that this example helps to find a solution to the problem.

Hi,
I'm facing the same issue on version 1.7.1
I guess it could be related to this dependency problem https://www.mkyong.com/java/log4j2-failed-to-load-class-org-slf4j-impl-staticloggerbinder/

Looks like this was introduced on 1.6.10 -> https://github.com/spotbugs/spotbugs-gradle-plugin/blob/1.6.10/src/main/java/com/github/spotbugs/SpotBugsPlugin.java#L189

Previously, no trace of sl4fj

This problem is also happening for me.

It appears to be some interaction between the spring boot gradle plugin and this plugin.

I tried adding slf4j-api and logback-classic to the classpath used by Spotbugs but it did not fix the issue, not sure why.

[sunzihao128858]

add "org.slf4j:slf4j-nop:1.7.25" to the build.gradle

[MarcJose]

I tried that before but it did not help.

Still a problem. Can confirm it's something related to the spring boot plugin. Here's my build.gradle for reference:

plugins {
	id 'application'
	id 'idea'
	id 'com.github.ben-manes.versions' version '0.27.0'
	id 'com.github.spotbugs' version '2.0.1'

	id 'io.spring.dependency-management' version '1.0.8.RELEASE'

	implementation 'org.springframework.boot:spring-boot-dependencies:2.2.1.RELEASE'
	implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
}

version = '0.1.0-SNAPSHOT'
application {
	mainClassName = 'foo'
}

pmd {
	ruleSets = ['java-quickstart']
}
spotbugs {
	toolVersion = '4.0.0-beta4'
}

I am getting this with micronaut 1.3.0.M1. I also have spring's dependency management plugin. I'm not sure if that could be a culprit here since others are having issues with their spring plugins (well spring boot) as well.

here's a portion of my build.gradle

plugins {
  id "com.github.spotbugs" version "3.0.0"
  id "com.github.johnrengelman.shadow" version "5.2.0"
  id "io.spring.dependency-management" version "1.0.8.RELEASE"

Please try the latest version 4.0.x instead of 3.0.0.

[daggerok]

we cannot use > 2.0.0, because of multi-module mono-repo. how to fix that problem with gradle plugin 2.0.0?

[KengoTODA]

Duplicate of #136

[KengoTODA]

I'll close this duplicated issue. use #136 instead.

[eceeb]

still the same problem here
