外部Maven回购和詹金斯

Question

I have an external jar(meaning not available in a public repo), that i want o include in my build. I used the instructions found on this site: http://charlie.cu.cc/2012/06/how-add-external-libraries-maven/ and it works, when I do mvn install in my PC. But when I am building the maven project using Jenkins, i get the following error:

Executing Maven: -B -f D:\\Program Files (x86)\\Jenkins\\workspace\\rmy job\\pom.xml install [INFO] Scanning for projects... [INFO]

[INFO]

[INFO] Building xxxxxx 0.0.1-SNAPSHOT [INFO]

[WARNING] The POM for sqljdbc:sqljdbc_4.0:jar:v4 is missing, no dependency information available

The pom that i am using has these entries for repositories:

    <repositories>
<repository>
    <id>codehaus</id>
    <url>http://repository.codehaus.org/org/codehaus</url>
</repository>

<!-- In Project repository -->
<repository>
    <id>in-project</id>
    <name>In Project Repo</name>
    <url>file://${project.basedir}/libs</url>
</repository>

Any ideas why this is happening?

Answer 1

After some tries, i did the following workaround in pom.xml

<repository>
    <id>in-project</id>
    <name>In Project Repo</name>
    <url>file://${project.basedir}/libs</url>
</repository>

and

<dependency>
    <groupId>sqljdbc</groupId>
    <artifactId>sqljdbc_4.0</artifactId>
    <version>v4</version>
      <scope>system</scope>
    <systemPath>${project.basedir}/libs/sqljdbc/sqljdbc_4.0/v4/sqljdbc_4.0-v4.jar</systemPath>
</dependency>

This means that the system path is needed as a whole and not just

 <url>file://${project.basedir}/lib</url>

as it was mentioned above. By this "workaround" I got it to work both locally and remotely (Jenkins-Git)

Answer 2

As a general rule I always strongly recommend to

• use a Maven Repository Manager such as Nexus
• only manage repositories in the Maven Repository Manager, not in the POMs
• use the Maven Repository Manager to host third-party libraries not available from any other repository
• configure your settings file

This is a key to get stable and reproducible builds - even when one of the repositories is temporarily unavailable.

Answer 3

Actually that might be hppen that it can't get the jar from lib.

tyr it with other way.

1. right click project
2. select property
3. java build path
4. select Lib
5. add external jar and put set path of your jar files
6. finish
7. clean and build your project.

OR

    <repositories>
        <repository>
        <id>local123</id>
        <name>localRepo</name>
        <url>file://${project.basedir}/lib</url>
        </repository>
     </repositories>

try putting this code in pom.xml file.

hope your problem can be resolve using this.
