由于 jenkins 中的本地修改，Maven Release Plugin 中止准备

Question

问题：

当我执行 maven 发布插件的准备目标时出现错误

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.3.2:prepare (default-cli) on project my-artifact-id: Cannot prepare the release because you have local modifications :

[ERROR] [my-project-name\src\main\java\some\packages\SomeJavaSourceFile.java:modified]

...

[ERROR] [my-project-name\src\main\java\some\packages\SomeOtherJavaSourceFile.java:modified]

大约 20 个文件。

详情

发布插件是从 Jenkins 执行的。
SVN配置为"always check out a fresh copy"
Maven 发布插件与目标一起使用-Dresume=false clean release:prepare release:perform
修改的文件是在上次提交中修改的。
执行准备目标时出现错误：

[INFO] --- maven-release-plugin:2.3.2:prepare (default-cli) @ artifact-id
发布插件运行过去11次成功（但有时第一次不行，第二次不行）

类似问题

为什么其他问题没有帮助：

How to disable maven release plugin check local modifications?: 我不想忽略这个文件。他们应该是发布的一部分
Maven release:prepare : Cannot prepare the release because you have local modifications: 修改的文件不在目标目录下，也不是修改的pom.xml-文件

Answer 1

概览

提交的文件只有 \n( = lf = line feed) 作为以 subversion 结尾的行。他们是在 windows 机器上签出的，所以结尾变成了 \r\n(= crlf = carriage return and line feed)。因此文件已更改为 "modified"。要修复该文件，请直接以 \r\n-ending 结尾。

查找方式

在 Jenkins 上重新签出后，您可以运行 "svn status" 作为脚本查看，文件被标记为“已修改”的确切信息。
当您调用 "svn diff" 时，您会看到每个文件的每一行都不同，但您看不到任何差异 => 不可见的变化
从 jenkins 工作区打开一个这样修改过的文件，从 svn repo 打开一个这样的修改文件，并使用可以可视化不可见字符的编辑器查看它们（例如，工具栏中带有 "show all characters" 的 Notepad++）

理由

发生这种情况的原因是 git-svn 的错误使用。我在没有更改 "autocrlf" 设置的情况下使用 git-svn 检查了该文件。 Git 在提交到本地回购时将结尾更改为 \n。当推送到 svn 时，行结尾仍然是 \n.

修复

使用 svn 客户端结帐，更改行结尾，提交。
或在git中将"autocrlf"设置为false。使用 git-svn 检查，更改行尾，dcommit。

以后如何避免

Git 有一个设置 "autocrlf"。关闭它似乎可以解决问题

Answer 2

执行以下步骤后已解决

scm 标签（连接、developerconnection 和 url）和发布插件从父 pom 移动到子 pom。
在 maven 命令中使用了 -B 选项示例：mvn -B -f pom.xml -DdevelopmentVersion=<developmentVersion> -DreleaseVersion=<releaseVersion> -Dusername=<scmUserName> -Dtag=<releaseVersion> -Dresume=false release:prepare release:perform versions:use-latest-releases -Dpassword=<scmPassword>

由于 jenkins 中的本地修改，Maven Release Plugin 中止准备
