I`ve changed jdk to a 9 version in my project and then collided with an error :
Error:java: java.lang.NoClassDefFoundError: javax/annotation/Generated
I try to solve it by the adding following to pom.com but it wasn`t work for me:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${version.compiler.plugin}</version>
<configuration>
<!-- fork is needed so compiler args can be used -->
<fork>true</fork>
<compilerArgs>
<arg>-J--add-modules</arg>
<arg>-Jjava.annotations.common</arg>
</compilerArgs>
</configuration>
</plugin>
Does it have other way to solve?
Add an artifact containing the classes you need to the classpath.
It appears that the javax.annotation API is what you need. See https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api/1.3.2 for details. You can add the following dependency to your project as any other and it should be present:
<!-- https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api -->
<dependency>
<groupId>javax.annotation</groupId>
<artifactId>javax.annotation-api</artifactId>
<version>1.3.2</version>
</dependency>
Remember to remove the compiler arguments!
implementation 'javax.annotation:javax.annotation-api:1.3.2'
annotationProcessor("javax.annotation:javax.annotation-api:1.3.2")
From 2020 onwards, the javax.* modules have been transitioned to jakarta. So the 2020+ proof dependency declaration is now:
<groupId>jakarta.annotation</groupId>
<artifactId>jakarta.annotation-api</artifactId>
