找不到工件com.oracle.toplink：toplink：jar：10.1.3

Question

I am trying to create a spring 4 project from scratch and maven is unable to resolve the dependency of com.oracle.toplink:toplink:jar:10.1.3

The following are the repositories that I have set in the pom.xml

<repositories>
    <repository>
        <id>repo2.maven.org</id>
        <name>repo2.maveng.org</name>
        <url>http://repo2.maven.org/maven2</url>
    </repository>
    <repository>
        <id>repo1.maven.org</id>
        <name>repo1.maven.org</name>
        <url>http://repo1.maven.org/maven2</url>
    </repository>
    <repository>
        <id>java.net</id>
        <name>java.net</name>
        <url>http://download.java.net/maven/2</url>
    </repository>
    <repository>
        <id>com.springsource.repository.bundles.release</id>
        <name>EBR Spring Release Repository</name>
        <url>http://repository.springsource.com/maven/bundles/release</url>
    </repository>
    <repository>
        <id>com.springsource.repository.bundles.external</id>
        <name>EBR External Release Repository</name>
        <url>http://repository.springsource.com/maven/bundles/external</url>
    </repository>
    <repository>
        <id>repo.spring.io</id>
        <name>repo.spring.io-releases</name>
        <url>http://repo.spring.io/ext-release-local</url>
    </repository>
</repositories>

Questions:

• Which repo should I add to make sure maven resolves this dependency?
• Usually, how does one know which repo has a particular artifact belong to?

• The error message I see is below. Does this error mean Maven did not try looking up for it in other repositories mentioned?

  Could not find artifact com.oracle.toplink:toplink:jar:10.1.3 in repo2.maven.org ( http://repo2.maven.org/maven2 ) -> [Help 1]

Answer 1

The is Oracle toplink - toplink-10.1.3 in maven's Central repository http://repo1.maven.org/maven2 . So you just only need to add the dependency in pom.xml, not the repository.

<dependency>
    <groupId>com.oracle.toplink</groupId>
    <artifactId>toplink</artifactId>
    <version>10.1.3</version>
</dependency>
