Question

I set up Neo4j-Kernel 1.9M04 and Spring-Data-Neo4j 2.1.0 RELEASE.

More precisely, here my dependencies (from my SBT file):

    "org.springframework" % "spring-aop" % "3.2.0.RELEASE",
    "org.springframework" % "spring-aspects" % "3.2.0.RELEASE",
    "org.springframework" % "spring-beans" % "3.2.0.RELEASE",
    "org.springframework.data" % "spring-data-commons-core" % "1.4.0.RELEASE",
    "org.springframework" % "spring-expression" % "3.2.0.RELEASE",
    "org.springframework" % "spring-jdbc" % "3.2.0.RELEASE",
    "org.springframework" % "spring-orm" % "3.2.0.RELEASE",
    "org.springframework" % "spring-test" % "3.2.0.RELEASE",
    "org.springframework" % "spring-tx" % "3.2.0.RELEASE",
    "org.springframework.data" % "spring-data-neo4j" % "2.1.0.RELEASE" excludeAll(
      ExclusionRule(organization = "com.sun.jdmk"),
      ExclusionRule(organization = "com.sun.jmx"),
      ExclusionRule(organization = "javax.jms")
      ),
    "org.neo4j" % "neo4j" % "1.9.M04",
    "org.neo4j" % "neo4j-kernel" % "1.9.M04" % "test" classifier "tests" classifier "",
    "asm" % "asm-all" % "3.1",
    "org.specs2" %% "specs2" % "1.13" % "test" withSources(),
    "org.springframework.data" % "spring-data-neo4j-rest" % "2.1.0.RELEASE"

At runtime, trying to autowire a neo4j repository, I’ve got this stack:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.data.neo4j.config.Neo4jConfiguration#0': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/neo4j/kernel/impl/core/LockReleaser

I noticed that the class org/neo4j/kernel/impl/core/LockReleaserhas disappeared from Neo4J 1.9M0X.

It seems that the error provides from "org.springframework.data" % "spring-data-neo4j-rest" % "2.1.0.RELEASE"

How could I fix this?

Answer 1

Looks like spring-orm was build against different version of neo4j than you’re trying to use at runtime (they are incompatible).

Possible solutions:

• Use older version of neo4j.
• Build spring-orm yourself against your current version of neo4j. Likely you will have to migrate spring-orm yourself.
