Question

我希望有人可以提供一些见解，一些建议，甚至只是指出我试图解决这个奇怪问题的方向。

在某些环境中，例如我们的Jenkins服务器，甚至有时在开发人员机器上，如果从git repo克隆这个特定项目，然后在其上运行maven构建，则构建失败，打印大量递归栈跟踪并且抛出stackoverlow错误。

$ git clone git@git@bitbucket.org:company/project.git
$ cd project
$ mvn clean install -DskipTests
$ <Fails with stacktrace seen below>

在构建失败的情况下，如果我使用“cp -r”制作项目目录的副本，然后在新创建的目录中运行构建...构建成功没有任何问题。（！）

$ cp -r project project_copy-r
$ cd project_copy-r
$ mvn clean install -DskipTests
$ <Build succeeds with no errors>

如果我使用“cp -a”制作项目目录的副本，然后在新复制的目录中运行maven构建，则构建将失败并返回与原始目录相同的错误。（!!）

$ cp -a project project_copy-a
$ cd project_copy-a
$ mvn clean install -DskipTests
$ <Fails with stacktrace seen below>

如果我使用“cp -rp”制作项目目录的副本，然后在新创建的目录中运行构建，则构建将再次失败并出现相同的错误。

$ cp -rp project project_copy-rp
$ cd project_copy-rp
$ mvn clean install -DskipTests
$ <Fails with stacktrace seen below>

因此......使用“-a”或“-rp”标志复制的副本与复制命令中的“-r”标志之间的区别是不同的。这里显而易见的选择是，项目目录中的某些内容具有过于严格的权限，只有在使用“-r”标志时才会被删除。

但是，如果我运行“sudo chmod -R 755 project_copy-rp”，我仍然会遇到相同的构建错误。如果我然后运行“sudo chown -R me：me project_copy-rp”

那么同上

$ sudo chmod -R 755 project_copy-rp 
$ cd project_copy-rp
$ mvn clean install -DskipTests
$ <Fails with stacktrace seen below>
$
$ chown -R me:me ../project_copy-rp 
$ mvn clean install -DskipTests
$ <Fails with stacktrace seen below>

此外，一旦使用“-a”或“-rp”复制了项目文件夹，无论隐藏什么问题，似乎都会对副本“锁定”。此时仅使用“-r”标志重新复制先前创建的目录不会导致构建错误消失。

$ cp -a project project_copy-a
$ cp -r project_copy-a project_copy-a-r
$ cd project_copy-a-r
$ mvn clean install -DskipTests
$ <Fails with stacktrace seen below>

在Jenkins服务器上，构建应该由包含Maven 3和Oracle Java 8的docker镜像完成。构建再次失败并具有相同的堆栈跟踪。为了测试这个问题，我git将项目的副本克隆到Jenkins服务器上的主目录，安装了Maven 3和Oracle Java 8，并从那里运行了构建。它成功了，没有错误。

正如我所说 - 如果有人有任何想法，我会很感激。

最后6行重复几十次，直到堆栈跟踪结束。 maven构建似乎进入递归循环，直到发生堆栈溢出。

Answer 1

你有一个创建目录循环的符号链接，你有一个插件可以遍历所有类进行修改（这里可能是aspectj-maven-plugin）。该插件可能正在使用一些递归算法来遍历目录，因此由于目录循环（使其看起来有无数个目录），它将达到堆栈溢出。

执行cp -r时，您不会保留符号链接，这就是为什么要修复它，但cp -a和cp -rp都会保留链接，你将继续失败。

您应该在项目中搜索符号链接，找到负责人并将其删除。

maven build在某些环境中失败，但随后成功获取同一目录的副本
