Unable to install 5.2.0 on Windows 10 professional

[donzelch]

Launcher fails launching because a path or the command itself is too long.

Tried alternative installations : unable anyway to initialize any database.

Can you give us some more detail? e.g. the paths involved and any relevant error messages/logs?

The following line, on Windows 10 doesn't work if the BASEDIR path is longer than 15 characters.

%JAVACMD% %JAVA_OPTS% -Xms128m -Dfile.encoding=UTF-8 -Dlog4j.configurationFile="%BASEDIR%"/etc/log4j2.xml -Dexist.home="%BASEDIR%" -Dexist.configurationFile="%BASEDIR%"/etc/conf.xml -Djetty.home="%BASEDIR%" -Dexist.jetty.config="%BASEDIR%"/etc/jetty/standard.enabled-jetty-configs -classpath %CLASSPATH% -Dapp.name="launcher" -Dapp.repo="%REPO%" -Dapp.home="%BASEDIR%" -Dbasedir="%BASEDIR%" org.codehaus.mojo.appassembler.booter.AppassemblerBooter %CMD_LINE_ARGS%

This is probably due to the length of the path in some jar file. I solved it by copying the installation folder into the root folder.

@donzelch Did your BASEDIR path previously have spaces in it?

[donzelch]

No. It was G:\Extrasoft\existdb_5.2.0. After initializing the platform, I moved it to the original place and everything is working fine. I had previously activated the "long file names" option of Windows 10 because I know that long path into jar files often create problems when copying Eclipse based RCP applications. On Windows 7, using 7zip for moving a RCP application from one disk to another was quite mandatory.

So may be, the problem is just with the length of the command itself. I haven't tried, for example, to rename the "launcher.bat" into "cmd.bat". Sometime Microsoft is keeping old interfaces for compatibility reasons.

@donzelch not quite sure what we can do here. Windows does have a limitation on the command line length when executing from cmd.exe. For that exact reason we previously had to adopt AppassemblerBooter, so that it would load the classpath dynamically for us rather than it becoming very long.

[adamretter]

@donzelch Do you think that providing PowerShell alternatives to the .bat files would solve this problem?
