MINGW Git bash中的Maven错误:无法找到或加载主类org.codehaus.plexus.classworlds.launcher.Launcher [英] Maven error in MINGW Git bash: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

问题描述

我知道这个问题已经在多个问题中进行了讨论，但是没有答案可以解决我的具体问题.

I'm aware of the fact that this issue has been discussed in several questions but no answer solved my specific issue.

我已经安装了Git bash和Maven，并且正在尝试使用Git bash执行Maven.它因提到的错误而中止.

I have installed Git bash and Maven and I'm trying to execute Maven with Git bash. It aborts with the mentioned error.

我的系统环境:

Windows 7
Git 2.13.3
Maven 3.5.0

必需的用户变量:

HOME=%HOMEPATH%
M3_HOME=%MAVEN_HOME%
MAVEN_HOME=path-with-no-blanks
Path=%MAVEN_HOME%\bin

Maven在Windows命令提示符和Cygwin上运行良好.只有基于MINGW的Git bash失败.

Maven works fine on Windows command prompt and Cygwin. Only MINGW-based Git bash fails.

我在以下位置检查了bash脚本mvn:C:\path\to\maven\bin

I examined the bash script mvn under: C:\path\to\maven\bin

通过设置日志输出并检查MAVEN_HOME值何时丢失，我发现这些语句(甚至是JAVA_HOME)也将其清除:

By setting log outputs and by checking when MAVEN_HOME value gets lost I found out that it gets cleared by these statements (even JAVA_HOME):

# For MinGW, ensure paths are in Unix format before anything is touched !!!HERE MAVEN_HOME value is getting lost!!!
if $mingw ; then
  [ -n "$MAVEN_HOME" ] &&
    MAVEN_HOME=`(cd "$MAVEN_HOME"; pwd)`
  [ -n "$JAVA_HOME" ] &&
    JAVA_HOME=`(cd "$JAVA_HOME"; pwd)`
  # TODO classpath?
fi

在另一台Windows计算机(Maven和Git的不同版本)上，相同的行略有不同:

On another Windows machine (different version of Maven and Git) the same lines are a bit different:

M2_HOME="`(cd "$MAVEN_HOME"; pwd)`"

代替:

MAVEN_HOME=`(cd "$MAVEN_HOME"; pwd)`

首先，我认为这是由于引号字符引起的.但是，运行正常的Windows计算机甚至可以与我出现故障的Windows计算机中的新脚本一起很好地运行.我还尝试安装旧的Git或旧的Maven-没有帮助.

First, I thought it's due to the kind of quotation characters. But the working Windows machine even runs well with the new script from my failing Windows machine. I also tried to install the old Git or an older Maven - nothing helps.

为什么提到的bash脚本行清除了MAVEN_HOME变量?

Why does the mentioned bash script line clears the MAVEN_HOME variable?

推荐答案

一段时间以来，我一直得到完全相同的错误，直到我意识到这是由我的防病毒软件(Comodo)引起的.如果我退出/禁用了Comodo，Git bash 甚至将无法正常工作.

I was getting the exact same error for a while until I realized that it was being cause by my antivirus (Comodo). Git bash would not work properly even if I had exited/disabled Comodo.

因此，如果您有Comodo，请尝试按照以下步骤解决该错误(如果您不这样做，则可以尝试使用所使用的任何防病毒/防火墙执行类似的操作):

So if you have Comodo, try following these steps to fix the error (if you don't then maybe try performing something similar with whatever antivirus/firewall you are using):

1. Comodo->设置->文件评级->添加文件夹(Git文件夹).最终添加了超过5000个受信任的文件(但它有助于解决此问题).

1. Comodo->Settings->File Rating-> Add Folder (Git Folder). This ended up adding over 5000 trusted files (but it helped fix the issue).

Comodo-> Settings-> Advanced Protection-> Miscellaneous->，并选中不要在...中检测到shellcode注入".我将整个Git文件夹添加到了shellcode注入中.

Comodo->Settings->Advanced Protection->Miscellaneous-> and find the checkmark "Don't detect shellcode injections in...". I added the entire Git Folder to shellcode injections.

我在Comodo-> Settings-> containment->"Auto-containment"中将git文件夹设置为"ignore"

I set the git folder to "ignore" in Comodo->Settings->containment->"Auto-containment"

我要补充一点，我不确定是否需要所有步骤，因此请随意一个接一个地执行它们，看看有什么帮助.

I'll add that I'm not sure if all of the steps are required, so feel free to perform them one by one and see which helps.
