How do I configure SLF4J?
To configure SLF$J SLF4J in Gradle project:
Add a log4j-test.properties under the directory of the java test.
- Add the following snippets into your
build.gradle
file.Code Block test { systemProperty "log4j.configuration", "log4j-test.properties" } dependencies { shadow library.java.slf4j_api shadow library.java.slf4j_log4j12log4j14 // or shadow library.java.slf4j_jdk14jdk12 }
Note: as of Beam 2.53.0, Beam does not support slf4j 2.x. Make sure your slf4j dependencies are of version 1.x
- The second dependency
shadow library.java.slf4j_log4j12log4j14
is not necessary if another library already provides this dependency. Check the dependency included in the dependency tree, execute:
Code Block ./gradlew dependencies.
Check If you encounter an error message like the following.
Panel borderStyle dashed SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation- If so, it means there is no SLF4J.Add
library.java.slf4j_log4j12
orlibrary.java.slf4j_jdk14
in thebuild.gradle
file.
- If so, it means there is no SLF4J.Add
To configure SLF4J in Maven project
Configure the dependency in pom.xml:
Code Block <properties> <slf4j.version>1.7.30</slf4j.version> </properties> <dependencies> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-jdk14</artifactId> <version>${slf4j.version}</version> <!-- When loaded at runtime this will wire up slf4j to the JUL backend --> <scope>runtime</scope> </dependency> <dependencies>

A workaround that did the trick. Since many things were tried in the process and no clear way to reproduce the error, this might not be the correct or best step. Update steps if you find a shorter or cleaner way to do the trick.
Refresh
tradle
gradle
project in IntelliJ.- Close Intellij.
Clean build project from the console. Execute>
Code Block ./gradlew clean cleanTest build -x testWebsite -x :rat -x test
- Open IntelliJ.
Build errors due to inconsistent Gradle cache
Sometimes build fails even for the main (master) branch either using IntelliJ or command line. If it worked before but now consistently failing, most likely this is due to inconsistent Gradle cache. It could happen when switching branches back and forth. Run the build Gradle command line with "--rerun-tasks" would do the trick.
