Maven: missing net.sf.json-lib

I found net.sf.json-lib in the central repository. Copy-pasted the dependency (with version 2.3), and then when I build I get this error:

[INFO] Unable to find resource 'net.sf.json开发者_JAVA百科-lib:json-lib:jar:2.2.3' in repository central (http://repo1.maven.org/maven2)

[ERROR] BUILD ERROR
[INFO] ---------------------------------------------------------
[INFO] Failed to resolve artifact.

Missing:
----------
1) net.sf.json-lib:json-lib:jar:2.3

  Try downloading the file manually from the project website.

I tried using version 2.2.3, but I'm getting the same error. Why am I getting this error? I can override it by installing it locally, but I want to understand what the problem is.

Edit - I deleted the package from my local repository, and tried again, this time getting a checksum error. I guess I should file a bug report with json-lib.

[WARNING] *** CHECKSUM FAILED - Error retrieving checksum file for net/sf/json-lib/json-lib/2.3/json

Looking at the maven-central repo, you need to specify a classifier for this dependency.

Either jdk13 or jdk15, like this:

<dependency>
    <groupId>net.sf.json-lib</groupId>
    <artifactId>json-lib</artifactId>
    <version>2.4</version>
    <classifier>jdk15</classifier>
</dependency>

For gradle as sample

compile 'net.sf.json-lib:json-lib:2.4:jdk15'

OR

compile group: 'net.sf.json-lib', name: 'json-lib', version: '2.4', classifier: 'jdk15'

I searched for more classifier's could not find anything other than jdk15 (don't go looking or jdk16 or jdk17)

Barring khimarbaise's comment about trustworthiness, you can install it locally using maven install:

• http://maven.apache.org/plugins/maven-install-plugin/examples/specific-local-repo.html

mvn install:install-file  -Dfile=path-to-your-artifact-jar
                          -DgroupId=your.groupId
                          -DartifactId=your-artifactId
                          -Dversion=version
                          -Dpackaging=jar
                          -DlocalRepositoryPath=path-to-specific-local-repo

For ivy users, after trying many different iterations to configure my ivy.xml to properly find this dependency, this finally worked for me:

  <dependency org="net.sf.json-lib" name="json-lib" rev="2.4">
        <artifact name="json-lib" url="http://repo1.maven.org/maven2/net/sf/json-lib/json-lib/2.4/json-lib-2.4-jdk15.jar"/>     
    </dependency>
