Crashes once I get to the loading modules.

[SarahHancock4765]

I have downloaded the most recent version of Netbeans, the environment crashes upon reaching the loading modules phase. It doesn't leave a crash log popup, it just cancels itself out. I have to get the environment working for my computer science class, so if I could get help I would greatly appreciate it.

make sure a JDK is in the path. OpenJDK 17 would be the latest long term support release for example.

you can also configure the netbeans_jdkhome property in netbeans/etc/netbeans.conf if you want to set it directly which is often easier.

Default locations of userdir and cachedir:

(http://wiki.netbeans.org/FaqWhatIsUserdir)

On Windows ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher

with "\NetBeans" where is user's

value of "AppData" key in Windows Registry under

"HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders"

and ${DEFAULT_CACHEDIR_ROOT} will be replaced by the launcher

with "\NetBeans\Cache" where is user's

value of "Local AppData" key in Windows Registry under

"HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders"

On Mac ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher

with "~/Library/Application Support/NetBeans" and

${DEFAULT_CACHEDIR_ROOT} with "~/Library/Caches/NetBeans"

On other systems ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher

with "/.netbeans" and ${DEFAULT_CACHEDIR_ROOT} with "/.cache/netbeans"

You can also use ${HOME} variable which will be replaced with

user.home JVM system property value. This variable is valid only in

netbeans_default_userdir and netbeans_default_cachedir properties.

NOTE: If you specify a non-default userdir path on command line

(--userdir option) and don't specify a cachedir path (--cachedir option),

cachedir will be in "/var/cache".

Cachedir must be different from userdir. The same cachedir and userdir

would cause problems.

netbeans_default_userdir="${DEFAULT_USERDIR_ROOT}/15"
netbeans_default_cachedir="${DEFAULT_CACHEDIR_ROOT}/15"

Options used by NetBeans launcher by default:

(can be overridden by explicit command line switches)

Note that default -Xmx is selected for you by the JVM automatically.

You can find these values in var/log/messages.log file in your userdir.

The automatically selected value can be overridden by specifying -J-Xmx

here or on the command line.

JDK 11 made GTK 3 default on Linux. Unfortunately it makes

NetBeans ugly on Linux with the default GTK+ Look and Feel,

as a workaround -J-Djdk.gtk.version=2.2 has been added to the

default command line arguments.

Default location of JDK:

(set by installer or commented out if launcher should decide)

It can be overridden on command line by using --jdkhome

Be careful when changing jdkhome.

There are two NetBeans launchers for Windows (32-bit and 64-bit) and

installer points to one of those in the NetBeans application shortcut

based on the Java version selected at installation time.

netbeans_jdkhome="C:\Program Files\Java\jdk-18.0.2.1"

Additional module clusters:

using ${path.separator} (';' on Windows or ':' on Unix):

#netbeans_extraclusters="/absolute/path/to/cluster1:/absolute/path/to/cluster2"

The java is looking in the right place as far as I am aware.
