Below is my java class
import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class App {
public static void main(String[] args) {
String[] springConfig =
{
"spring/batch/jobs/job-hello-world.xml"
};
ApplicationContext context =
new ClassPathXmlApplicationContext(springConfig);
JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
Job job = (Job) context.getBean("helloWorldJob");
try {
JobExecution execution = jobLauncher.run(job, new JobParameters());
System.out.println("Exit Status : " + execution.getStatus());
} catch (Exception e) {
e.printStackTrace();
}
}
}
I am getting error in import statements in App.java class. "The import org.springframework cannot be resolved." I clearly mentioned dependencies in POM.xml still my java class cannot pick dependency from there.
You need to follow a few steps to debug properly.
1) mvn clean dependency:tree Take a look at the output to see exactly what you get and verify your dependencies are all there.
2) mvn clean compile. Does this fail? If not does that mean you only get the error in Eclipse?
You mentioned in a comment "And I run both commands above but I am getting this error". Did mvn clean compile work? Or did you get an error for that as well? If it worked then it's just an IDE problem and I'd look at the m2eclipse plugin. Better still, use IntelliJ as the free version has better maven support than Eclipse ;-)
Some style things ...
People often add too many dependencies in their pom file when they don't need to. If you take a look at a couple of links in mavenrepository.com you can see that spring-oxm and spring-jdbc both depend on spring-core so you don't need to add that explicitly (for example). mvn clean dependency:tree will show you what is coming in after all of that, but this is more tidying.
spring-batch-test should be test scope.
Finally my issue got resolved. I was importing the project as "Existing project into workspace". This was completely wrong. After that I selected "Existing Maven project" and after that some few hiccups and all errors were removed. In this process I got to learn so many things in Maven which are important for a new comer in Maven project.
The solution that worked for me was to right click on the project --> Maven --> Update Project then click OK.
My direct solution for this issue : right click the project --> Maven ---> Add Dependency == then choose the name or parent name of missing dependency
Add these dependencies
</dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>

Right click project name in Eclipse, -->Maven-->Select Maven Profiles... Then tick the maven profile you want to set. After click OK, Eclipse will automatically import the maven setting to your project. If you check your project's Property, you will find Maven Dependencies Library has been added.
This answer from here helped me:
You should take a look at the build path of your project to check whether the referenced libraries are still there. So right-click on your project, then "Properties -> Java Build Path -> Libraries" and check whether you still have the spring library JARs in the place that is mentioned there. If not, just re-add them to your classpath within this dialog.
org.springframework.beans.factory.support.beannamegenerator , was my error. I did a maven clean, maven build etc., which was not useful and I found that my .m2 folder is not present in my eclipse installation folder. I found the .m2 folder out side of the eclipse folder which I pasted in the eclipse folder and then in eclipse I happened to do this :-
Open configure build path maven Java EE integration Select Maven archiver generates files under the build directory apply and close
My project is up and running now.
if you're sure that your pom.xml is pretty good, then you have just to update the poject. right click on the project - Maven - update project. or simply alt+F5.
In my case I had to delete the jars inside .m2/repository and then did a Maven->Update Maven Project
Looks like the jars were corrupt and deleting and downloading the fresh jar fixed the issue.
I imported a project as 'Existing Maven Project' and was getting this issue.
Resolution: Changed Java Build Path of JRE System Library to Workspace defailt JRE [jdk 1.8]
Steps:
Right click on project -> build path -> configure build path -> Libraries Tab -> double click JRE System Library -> change to Workspace defailt JRE [jdk 1.8]
The only solution worked for me is add maven-compiler-plugin to the pom.xml
<project ...>
...
<build>
...
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<fork>true</fork>
<executable>C:\Program Files\Java\jdk1.7.0_79\bin\javac</executable>
</configuration>
</plugin>
</plugins>
</build>
...
</project>
Had the same problem in Eclipse STS. Changing the scope in the pom from "provided" to "compile" fixed the problem and when I changed it back everything was still OK.
In my case I used the below pom.xml file here
and it worked for me.
In my case, this issue was resolved by updating maven's dependencies:
