Issue
I am trying to use LoggerContext in my Java code.
Added the Maven dependency in pom.xml:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.17.1</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.17.1</version>
</dependency>
The piece of code that I am trying to add:
import org.apache.logging.log4j.core.LoggerContext;
LoggerContext context = (LoggerContext) LogManager.getContext(false);
File file = new File("path/to/a/different/log4j2.xml");
However, my import
statement errors out. I am using IntelliJ IDE and the 'Add Maven Dependency' option in the IDE that searches for the class also doesn't return any results for org.apache.logging.log4j.core.LoggerContext
I tried re-building the project from the IDE, but, that didn't help.
What am I missing?
Solution
The code looks good to my eyes, most likely IntelliJ hasn't pulled in the dependency.
To diagnose:
- run build via
mvn install
on command line. Inspect the output. If the build passes, this will limit the problem to IntelliJ - use
Reload All Maven Projects
on Maven tab in IntelliJ
