module-info - module not found: com.fasterxml.jackson.core

问题

I am trying to create a module-info file for my application but getting some issues with the com.fasterxml.jackson.core module when trying to build the application:

  1. ...\src\main\java\module-info.java:5: error: module not found: com.fasterxml.jackson.core
  2.     requires com.fasterxml.jackson.core;

module-info:

  1. module foo {
  2.     requires org.slf4j;
  3.     requires org.apache.commons.lang3;
  4.     requires com.fasterxml.jackson.annotation;
  5.     requires com.fasterxml.jackson.core;
  6.     requires com.fasterxml.jackson.databind;
  7. }

build.gradle:

  1. ...
  2. dependencies {
  3.     implementation 'org.slf4j:jcl-over-slf4j:2.0.7'
  5.     implementation 'com.fasterxml.jackson.core:jackson-annotations:2.15.1'
  6.     implementation 'com.fasterxml.jackson.core:jackson-core:2.15.1'
  7.     implementation 'com.fasterxml.jackson.core:jackson-databind:2.15.1'
  9.     implementation 'com.google.guava:guava:31.1-jre'
  11.     // Logging
  12.     implementation 'org.slf4j:slf4j-api:2.0.7'
  13.     implementation 'org.apache.commons:commons-lang3:3.12.0'
  14.     implementation 'commons-codec:commons-codec:1.15'
  16.     // http tools
  17.     api 'org.yamj:api-common:2.1'
  19.     // testing
  20.     testImplementation 'junit:junit:4.13.2'
  21.     testImplementation 'org.mockito:mockito-core:5.3.1'
  22. }
  24. tasks.withType(JavaCompile).configureEach {
  25.     options.encoding = 'UTF-8'
  26. }
  28. java {
  29.     withJavadocJar()
  30.     withSourcesJar()
  31. }
  32. ...

I'm using JDK 17 (Amazon Corretto) & Gradle 8.1.1

Does anyone know why this is happening and how to fix it? I've tried different versions of the jackson dependencies and still get the same issue.

If I remove

  1. requires com.fasterxml.jackson.core;
  2. requires com.fasterxml.jackson.databind;

from the module-info.java, it will try to build but get errors about visibility:

  1. ...\src\main\java\foo\app.java:4: error: package com.fasterxml.jackson.databind is not visible
  2. import com.fasterxml.jackson.databind.DeserializationFeature;
  3.                             ^
  4.   (package com.fasterxml.jackson.databind is declared in module com.fasterxml.jackson.databind, but module foo does not read it)

这是2.15.1版本中的一个额外模块信息文件1。这将在下一个版本2.15.2中修复。感谢@VGR指出，使用版本2.15.0将解决此问题，直到下一个版本发布为止。

There was an Extra module-info.class in 2.15.1. This will be fixed in the next release: 2.15.2. Thanks to @VGR for pointing out that using version 2.15.0 will fix this issue, until the next version has been released.
