neo4j社区建设失败了。为什么？

我遵循了Travis link中的所有步骤

我的maven版本是

Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.6.0_30, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-openjdk-amd64/jre
Default locale: en_IN, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-60-generic", arch: "amd64", family: "unix"

当我尝试使用maven构建时，我遇到了这个错误

[错误]无法执行目标org.neo4j.build.plugins:license maven plugin:3:check（检查许可证）on project neo4j内核：某些文件没有预期的许可证标头->[帮助1] org.apache.maven.lifecycle.LifecycleExecutionException:未能执行目标org.neo4j.build.plugins:许可证maven插件：3:检查（检查许可证）project neo4j内核：某些文件没有预期的许可证头

首先我尝试在windows中构建，然后在ubuntu 12.04中，在这两个版本中我都遇到了相同的错误

下面是错误堆栈跟踪

现在我该如何解决这个问题呢？即使与此错误相同，也请使用Java 7

首先构建

社区/许可证检查

子模块。

按照

在Windows上构建时，请使用

-Dlicensing.skip

避免与行尾相关的问题

---

通过在命令行中添加以下内容，可以跳过许可证标题检查：

-Dlicense.skip=true

仍然存在相同的错误。我遵循的步骤有什么错误吗。你能检查一下这个链接吗？我哪里出错了。linux也有同样的错误。为什么要扔它？
