Maven java.lang.NoClassDefFoundError: org/hibernate/query/Query

Question

I'm working on a project and it kept generating error when runing the project.

I need help to solve this issue please, thank you in advance.

This is my first time using Maven and Hibernate and it's giving tons of errors such as

java.lang.NoClassDefFoundError: org/hibernate/query/Query at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1407) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1215)

I have tried this solution it works (the servlet works too) for a little while then back to the same problem again.

Try running an mvn dependency:tree to see what your classpath looks like.

There is a compatibility matrix between hibernate, REST and other components. That means you have to use the right versions together . It's often non-trivial to figure out which ones to combine, but mvn dependency:tree -Dverbose will give you insight where you overwrite versions. These days, most platforms have a website to generate a compatible pom for you ( Quarkus , Spring, etc). But old-school war based deployments typically don't have that yet. Non-war based deployments of Hibernate with Rest look differently: here's an example .

A quick search shows that the class org.hibernate.query.Query existed in hibernate-core 5.2, but not in 5.6, where it got moved to org.hibernate:hibernate-search-orm.

Try adding a dependency on hibernate-search-orm too:

        <dependency>
          <groupId>org.hibernate</groupId>
          <artifactId>hibernate-search-orm</artifactId>
          <version>5.6.0.Final</version>
        </dependency>
