【中文标题】`mvn jgitflow:release-finish` 多模块构建中的错误（由于错误的编译顺序）

【英文标题】：Error in `mvn jgitflow:release-finish` mutli-module build (due to wrong compilation order)

【问题描述】：

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，我收到以下错误：

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。首先我跑了：mvn jgitflow:release-start，它报告了“构建成功”。结果看起来是正确的：

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，但这是它应该编译的文件。深入挖掘，我跑了mvn jgitflow:release-finish -e -X > ~/mygitflow.log 以下是部分结果：

Requested Dependency: org.jorlib:jorlib-core:jar:1.0-SNAPSHOT

NOTE: You may need to run this build to the 'compile' lifecycle phase, or farther, in order to build the dependency artifact.

模块jorlib-demo依赖于jorlib-core，所以在编译jorlib-demo之前必须先编译jorlib-core。由于某种原因，这不会发生。结果，它在某个外部存储库中搜索jorlib-core，最终因为找不到它而失败。

【参考方案1】：

原来这个问题是我的Maven版本引起的。我的系统运行 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) 版本默认附​​带后一个 Maven 版本。我现在已经升级到 Apache Maven 3.2.1。升级到 Maven 3 后，我在执行 jgitflow:release-finish 时确实遇到了以下错误消息：

Error: JAVA_HOME is not defined correctly. 
We cannot execute /usr/lib/jvm/java-8-oracle/bin/java/bin/java

这实际上禁止了代码被编译。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。
