----------------------------------------
Summary: Java Modular Application Project build fail on Windows OS
Key: NETBEANS-1788
URL: https://issues.apache.org/jira/browse/NETBEANS-1788
Project: NetBeans
Issue Type: Bug
Components: projects - Java 9 MultiModule
Affects Versions: 10.0
Environment: OS: Windows 10 Pro, 64bit
JDK: OpenJDK 11.0.1 Windows 64bit
NetBeans: 10vc4
Reporter: TAKAHASHI,Toru
h2. Problem
BUILD FAILED to build application project generated from 'Java Modular Project'
on Windows and include path element begin with 'E'.
{noformat}
compile:
Building jar: D:\work\Essen\dist\com.torutk.essen.jar
To run this application from the command line without Ant, try:
C:\tools\jdk-11.0.1/bin/java -modulepath D:\work\Essen\build\modules
com.torutk.essen.Main
D:\work\Essen\nbproject\build-impl.xml:1218:
java.util.regex.PatternSyntaxException: Illegal/unsupported escape sequence
near index 20
\QD:\work\Essen\build\modules\\E([^\\]+)\Q\\E.*\.class
at java.base/java.util.regex.Pattern.error(Pattern.java:2015)
:
{noformat}
Error on build-impl.xml is as follows:
{noformat}
<pathconvert property="module.name">
<fileset dir="${run.modules.dir}"
includes="**/${toString:main.class.relativepath}"/>
<regexpmapper
from="\Q${run.modules.dir.location}${file.separator}\E([^${file.separator.string}]+)\Q${file.separator}\E.*\.class"
to="\1"/>
</pathconvert>
{noformat}
in regexpmapper, if 'run.modules.dir.locaion' includes any directory name begin
with 'E', the 'E' following a file.separator (i.e. '\') is treated as ends
quoting '\E'.
So, trailing '\build' is treated as escape sequence '\b' and string 'uild'.
'\b' is available escape scequence.
Then, trailing '\modules' is treated as escape sequence '\m' and string 'odule'.
'\b' is illegal escape sequence.
h2. Reproducing Procedure
* [File]menu > [New Project] > [Java Modular Project]
* Name project begin with 'E' (for example, 'Essen')
* Add new module to the project
* Create Main class (with public static void main method)In this steps, build
project is succeed because of no main class is set to the project.
* Run project once.The main class is set to the project.
* Build project, then BUILD FAILED occurrs.
