imbennie opened a new issue, #619:
URL: https://github.com/apache/maven-mvnd/issues/619
This problem seems like #156 but has a little difference.
I had SDKMAN in my Cygiwn and have several java versions installed.
So Cygwin has its own `JAVA_HOME`.
```
~ » echo $JAVA_HOME
/home/Bennie/.sdkman/candidates/java/current
```
And when i checkout mvnd version
```
~ » mvnd -v
mvnd native client 0.7.1-windows-amd64
(97c587c11383a67b5bd0ff8388bd94c694b91c1e)
Terminal: org.jline.terminal.impl.jansi.win.JansiWinSysTerminal
Exception in thread "main" java.lang.RuntimeException: Could not get a real
path from path \home\Bennie\.sdkman\candidates\java\current

```
That's the problem what is.
I'm trying `mvnd -v` agin after edit `java.home` in the
`conf/mvnd.properties` with following, But still got the same error output
before.
```
java.home=/home/Bennie/.sdkman/candidates/java/8.0.322-tem
```
After read the #156 I find out maybe the @gnodet doesn't have a `JAVA_HOME`
in Cygwin itself which just copied from Windows one.
Thus I unset the JAVA_HOME and ran `mvnd -v` agin.
```
~ » unset JAVA_HOME
~ » mvnd -v
mvnd native client 0.7.1-windows-amd64
(97c587c11383a67b5bd0ff8388bd94c694b91c1e)
Terminal: org.jline.terminal.impl.jansi.win.JansiWinSysTerminal
Exception in thread "main" java.lang.RuntimeException: Could not get a real

```
This time the `java.home` path in output is point to our's one. Verified
that the `unset JAVA_HOME` operation is valid.
But the problem still does what it does.
I checked out the #156 bug-fixed details. Found out the `java.home` path
start with `\cygdrive\`, So edit `java.home` in the `conf/mvnd.properties`
again.
Then It's just worked.
```
java.home=/cygdrive/d/Tools/cygwin/home/Bennie/.sdkman/candidates/java/8.0.322-tem
~ » mvnd -v
mvnd native client 0.7.1-windows-amd64

```
Finally:
1. Is there a good way to solve this problem?
2. This is may be a bug? due the `java.home` property override by
`$JAVA_HOME`.
