dependencies.dependency.version' is missing error

Question

I am trying to create a bundle using apache maven. When I run mvn clean install command it is giving the below error:

dependencies.dependency.version' is missing for javax.servlet:servlet-api.jar

I have placed that ‘servlet-api.jar’ inside resource folder of my project

Could any anyone please tell where should I place that jar file?

UPDATE: Here is my pom.xml

Please show us your pom.xml. You obviously missed the <verion> for the <dependency> servlet-api. – Maure

Please find my pom.xml – Slub

Answer 1

You haven't added the version tag in dependency.

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>1.0.0</version>   //Add the version.
</dependency>

I had this same error for a slightly different reason.

My project uses dependency management (has 2 <dependencyManagement> sections for some reason) and has many modules and sub-modules.

Top level pom had:

    <dependencyManagement>
        <dependency>
            <groupId>org.apache.spark</groupId>
            <artifactId>spark-core_2.10</artifactId>
            <version>${spark.version}</version>
        </dependency>
    </dependencyManagement>

Sub-level pom had

    <dependencyManagement>
        <dependency>
            <groupId>org.apache.spark</groupId>
            <artifactId>spark-core_2.10</artifactId>
            <scope>provided</scope>
        </dependency>
    </dependencyManagement>

Leaf pom had

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-core_2.10</artifactId>
    </dependency>

To fix it I removed the <dependencyManagement> section from the mid-level pom and changed the leaf pom to have

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-core_2.10</artifactId>
        <scope>provided</scope>
    </dependency>

Answer 3

The message is quite clear: inside the dependencies element of your pom, you have a dependency element with the artefact javax.servlet:servlet-api.jar. And inside this dependency element, there must be a version element, but you didn't provide it.

<dependencies>
    <!-- Provided APIs -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>

        <!-- missing version here: -->
        <version>3.0</version>
    </dependency>
</dependencies>

Note that 3.0 is just an example. Provide the right version.

Thanks..Actually i have more than 20 dependencies in my POM. i knew groupid,artifactId but i dont know the version exactly. Is there any way to include? – Slub

any way to include what? You really should know which version of the servlet API you want to use. Nobody can guess for you. – Weird

I have found all the version except two version one is <dependency> <groupId>com.day.cq</groupId> <artifactId>cq-commons</artifactId> <version>5.5.0</version> </dependency> I knew the above version is correct. But maven unable to find it. But it gave alternate way to import it as mvn deploy:deploy-file -DgroupId=com.day.cq -DartifactId=cq-commons -Dversion=5.5.0 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id] what does it url, /path/to/file, id? Please guide me – Slub

Answer 4

You have to add the dependency and along with that version and scope is optional. the latest version of javax.servlet is 3.0-alpha-1 at this point of time.

<!-- https://mvnrepository.com/artifact/javax.servlet/servlet-api -->
   <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>servlet-api</artifactId>
      <version>3.0-alpha-1</version>
      <scope>provided</scope>
   </dependency>
