Neo4j 构建失败 WorkSync.java:[53,63] 不兼容的类型

Question

下载 Neo4j 最新代码，切换到 3.2.3 分支（最新稳定版）。然后执行 mvn clean install 进行构建，构建失败，错误信息如下：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project neo4j-primitive-collections: Compilation failure

这是啥原因呢？
