------------------------------------
Summary: Detection of JAVA_HOME fails due to bad quoting
Key: MWRAPPER-112
URL: https://issues.apache.org/jira/browse/MWRAPPER-112
Project: Maven Wrapper
Issue Type: Bug
Affects Versions: 3.2.0
Environment: Ubuntu 20.04, Java 17
Reporter: Ingo Karkat
I have a standard Ubuntu 20.04 Java installation ({{{}openjdk-17-jdk{}}} APT
package, {{/usr/bin/javac}} linked to
{{/usr/lib/jvm/java-17-openjdk-amd64/bin/javac}} via the update-alternatives
system, no {{JAVA_HOME}} set). Maven Wrapper 3.2.0 should detect that, but on
each invocation prints this warning:
{{Warning: JAVA_HOME environment variable is not set.}}
This is caused by excessive quoting (i.e. the {{{}\"{}}}):
{{javaExecutable="$(readlink -f "\"$javaExecutable\"")"}}
Apparently, that code has been in the codebase since the beginning, taken over
from the {{gradlew}} wrapper (which had the shell wrappers completely
rewritten; there are no remnants of this code found there any longer).
Pull request forthcoming.
