无法解决maven依赖：无法找到javax.persistence：ejb：jar：3.0-public-draft-20060327

Question

I'm trying to resurrect an old project. I wanted to use Maven to manage dependencies/build/etc., and I got pretty far, but now I'm running into an error that I can't seem to resolve, and that I can't seem to find anything about:

Failed to execute goal on project scanit: Could not resolve dependencies for project net.cbojar:scanit:jar:0.2: Could not find artifact javax.persistence:ejb:jar:3.0-public-draft-20060327 in maven2 ( http://repo1.maven.org/maven2/ )

It wants to download a ejb-3.0-public-draft-20060327.jar file, but that file does not exist in the repo .

I'm relatively new to maven, and I wanted to use this as practice, but I have now painted myself into a corner. Below is my pom.xml file.

Answer 1

Given that you are converting to Maven an existing project, you should respect the original dependencies. That means adding as a Maven dependency the exact same version of the original dependencies and excluding unused transitive dependency (since the original project doesn't need it and it works correctly then we can safely exclude them from the pom).

It turns out that javax.persistence:ejb:jar:3.0-public-draft-20060327 is a transitive dependency of org.hibernate:hibernate-annotations:3.1beta9 . If the original project doesn't need it, you can exclude it from the pom like this:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-annotations</artifactId>
    <version>3.1beta9</version>
    <exclusions>
        <exclusion>
            <groupId>javax.persistence</groupId>
            <artifactId>ejb</artifactId>
        <exclusion>
    </exclusions>
</dependency>

Answer 2

Remove your

<dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-annotations</artifactId>
            <version>3.1beta9</version>
</dependency>

And use:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-annotations</artifactId>
    <version>3.5.6-Final</version>
</dependency>

That is the dependency causing you that problem. It is from 2006. I also recommend you to update your dependencies version to the most up to date.

EDIT

As such an upgrade may break your code, and without further details, you should probably stick with a version closer to the one you are trying to use.

Check here for all hibernate-annotations versions available in maven repo.

Answer 3

You maybe need this dependecy declaration inside your project pom.xml:

    <dependency>
        <groupId>javax.persistence</groupId>
        <artifactId>ejb-3.0-public-draft</artifactId>
        <version>20050627</version>
        <type>pom</type>
    </dependency>
