`mvn jgitflow:release-finish` mutli-module build 出错（由于错误的编译顺序）
Error in `mvn jgitflow:release-finish` mutli-module build (due to wrong compilation order)
我正在尝试使用 JGitflow 为我的项目创建一个版本。不幸的是，当我 运行 mvn jgitflow:release-finish 时，出现以下错误：
Unable to find resource 'org.jorlib:jorlib-core:jar:1.0' in repository central (http://repo1.maven.org/maven2)
[WARNING] The dependency: org.jorlib:jorlib-core:jar:1.0 can't be resolved but has been found in the reactor.
我不确定如何解决这个问题。首先我 运行: mvn jgitflow:release-start 报告 "Build Successfull"。结果看起来正确：
jkinable@daedalus:~/workspace/javaIDEA/jORLib/jorlib$ git branch -avv
development 07e4c1f [origin/development: ahead 3] updating poms for 1.1-SNAPSHOT development
master f3240f9 [origin/master] Updated pom.xml
*release/1.0 f3240f9 Updated pom.xml
接下来我 运行 mvn jgitflow:release-finish 失败了。它似乎试图下载 jorlib-core-1.0.jar 但那是它应该编译的文件。深入挖掘这一点，我 运行 mvn jgitflow:release-finish -e -X > ~/mygitflow.log
这是部分结果：

原来这个问题是我的Maven版本问题。我的系统 运行s Java 1.8.0_45 和 Apache Maven 2.2.1 (rdebian-8)。在撰写本文时，最新的 Ubuntu LTS (14.04.2) 版本默认随附后一个 Maven 版本。我现在已经升级到 Apache Maven 3.2.1。升级到Maven 3后，在执行jgitflow:release-finish:
时，我做了运行，出现如下错误信息
Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/lib/jvm/java-8-oracle/bin/java/bin/java
这有效地禁止了代码的编译。注意奇怪的 bin/java/bin/java 部分。我仔细检查了我的 $JAVA_HOME，它正确地指向了 /usr/lib/jvm/java-8-oracle/。可以在此处找到此问题的解决方案：Having JAVA_HOME inconsistency issue with maven
我只是在我的主文件夹中创建了一个名为 .mavenrc 的文件，其中包含： export JAVA_HOME=/usr/lib/jvm/java-8-oracle
现在 Jgitflow 插件运行良好。
