奇怪的JPA编译错误

Question

I get the following compile errors when trying to use JPA 2.1 and EclipseLink 2.6

em.getCriteriaBuilder()

java: cannot find symbol symbol: method getCriteriaBuilder() location: variable em of type javax.persistence.EntityManager

Expression<Boolean>

java: type javax.persistence.criteria.Expression does not take parameters

TypedQuery<Foo> query = em.createQuery(queryString, Foo.class);

java: method createQuery in interface javax.persistence.EntityManager cannot be applied to given types; required: java.lang.String found: java.lang.String,java.lang.Class reason: actual and formal argument lists differ in length

My pom.xml contains the following dependencies for JPA

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>javax.persistence</artifactId>
        <version>2.1.0</version>
    </dependency>
    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>eclipselink</artifactId>
        <version>2.6.0</version>
    </dependency>

I can only think that the compiler is using a different JPA version where such methods I am trying to use above did not exist. However the pom clearly contains the 2.1 implementation.

These compilation errors are happening while I am attempting to convert a non maven project to an Intellij IDEA maven project (so everything worked before).

Answer 1

I believe the Google App Engine and Maven Facets of Intellij IDEA are incompatible. I chose to create the project from the skeleton-archetype of com.google.appengine.archetypes and ignored the GAE IDE integration feature. This solved the compliation errors.
