Minecraft server files generating in the wrong path on MacOS Big Sur - server

So I attempted to create my own minecraft server. Upon opening the .jar file, the files seem to generate in my [myusername] folder instead of my dedicated "server" file on the desktop. How can I change that?

Create a folder with your server-version.jar in it.
Then open your terminal, type "cd your/folder/path".
Then do "sudo java -jar server-version.jar". This will create the first few files. You'll need to agree to the EULA.
Finally, start your server using the previous command or using "sudo java -Xms512M -Xmx2048M -jar server-version.jar". You can modify the minimum and maximum ram which will be allocated to your Minecraft server.
This is what it looks like in my case using the latest spigot release :
cd /Users/******/Desktop/Minecraft\ Server
sudo java -jar spigot-1.16.4.jar
// Agree to the EULA in the EULA.txt
sudo java -Xms512M -Xmx2048M spigot-1.16.4.jar
All the files should be in the folder you created earlier.

Running MALLET on Windows; could not find or load main class cc.mallet.classify.tui.Text2Vectors

I'm trying to get MALLET running on a 64-bit Windows 10 Enterprise machine from the native command prompt (cmd.exe). (I tried doing everything with Git Bash, but got stuck even earlier in the process.)
What I've done:
Installed JDK 8u281 for 64-bit Windows
Downloaded and installed MALLET 2.0.8 in my C:\
Installed Apache Ant in my C:\Program Files (per this Medium post)
Created new environmental variables
Adjusted my path
Run ant within the MALLET folder (received BUILD SUCCESSFUL)
Run ant jar within the MALLET folder (received BUILD SUCCESSFUL)
Typed bin\mallet, which displays the MALLET commands
However, when I tried to create a .mallet file, using bin\mallet import-dir, I get the error message Error: Could not find or load main class cc.mallet.classify.tui.Text2Vectors.
I (and my students) will appreciate any help in figuring out how to get this running.
This looks like a classpath issue. I'm not sure how Java on Windows handles classpath now. Try setting %MALLET_HOME% to C:\Mallet-2.0.8, not the bin directory? The classes would be in %MALLET_HOME%\class also, perhaps try adding that to %PATH% or %CLASSPATH%?

Could not load the Tomcat server configuration at /usr/share/tomcat9/conf. The configuration may be corrupt or incomplete

I am using JSP for the 1st time. I am using tomcat9. While creating server, from eclipse, I get a window which shows Could not load the Tomcat server configuration at /usr/share/tomcat9/conf. The configuration may be corrupt or incomplete. Attached is the screenshot.
I installed 2 versions of tomcat9, but the error still remains.
Don't use an installed copy of Tomcat, its layout will have been modified and you won't have full read-write control over it. Use the tar/zip file you can download from tomcat.apache.org.
On Linux ubuntu, I went to the directory-> /usr/share/tomcat9/ by
cd /usr/share/tomcat9/
but conf folder is not there
My default installation path was /opt/tomcat/latest/
conf folder is inside that
So, I created a symbolic link from /usr/share/tomcat9/ to /opt/tomcat/latest/conf
I did cd /usr/share/tomcat9/
Then
sudo ln -s /opt/tomcat/latest/conf conf
Now everything worked and I can run helloworld program
To help others facing same problem->
Just find the conf folder and create a link to that folder
In windows create a shortcut; and in linux create a symbolink link.
In Linux:
sudo locate tomcat>>a.txt
vi a.txt
then search for conf in a.txt
/conf
identify a line containing both tomcat and conf
Find the location where system is searching for conf, in the error message.
For me, it was /usr/share/tomcat9/
Then link both the folders by creating symbolic link using ln -s command

How can I install MongoDB 3.X on Windows without admin rights?

I'm on a Windows 7 (64-bit) box and do not have admin rights.
It appears from the MongoDB download page (see http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/) that the latest version only an MSI install is available (no zip version).
I tried running the 3.0.4 MSI. I clicked custom so I could change the directory to install to. I used %USERPROFILE%\MyProgs\MongoDB-3.0.4, so no admin rights would be needed. It ran for a bit but then prompted me to enter admin credentials. I hit escape (like clicking on X at top right) to close the window. On other MSI installs this has worked. I tried it again and clicked "No" but in both cases received the message
MongoDB 3.0.4 2008R2Plus SSL (64 bit) setup was interrupted.
Your system has not been modified. [...]
This article does a GREAT job going through how to install MongoDB on Windows:
How to install mongoDB on windows?
My observation is that v2.4.14 is the last version that is available via the ZIP format. So for now, I'm using that version.
Is there any other way to install the MongoDB version 3.X MSI without admin rights?
NOTE: On the MongoDB Download page https://www.mongodb.org/downloads there is a link titled View Build Archive (it sends you here https://www.mongodb.org/dl/win32/x86_64-2008plus-ssl, and that site lists *.zip formatted files). I thought I had found my own solution to the question, but when I unzipped the files, and added the "bin" to my path and ran the programs (mongo, and mongod) I received an Windows Dialog that says:
mongod.exe - System Error
The program can't start because LIBEAY32.dll is missing from your
computer. Try reinstalling the program to fix the problem
I stopped here and posted this question. Thanks for any help.
For now I'm using the version that supported the zip format (v2.4.14) and that version does work.
NOTE2: The v2.4.14 zip formatted install doesn't have a file named LIBEAY32.dll), or I might have tried using that file with the newer version.
Yes, it is possible to install the latest MSI (including the one with SSL) without admin rights via command line.
msiexec /a mongodb-win32-x64-3.2.5.msi /qb TARGETDIR="C:\MongoDB"
This will copy the binaries into C:\MongoDB\MongoDB\Server\3.2\bin
I dislike long paths like that, so I create a symlink inside the folder:
cd C:\MongoDB
mklink /j bin C:\MongoDB\MongoDB\Server\3.2\bin
That will create a soft link as C:\MongoDB\bin (which you can add to your PATH environment variable).
mongo --version
mongod --version
Both should return version 3.2.5.
You can do this with most packages, we have to do similar with Python 2.7 and Node 4.4.3 MSI packages on work computers that do not have admin rights.
You can download the "legacy" version which is the unsigned non msi version as a zip. The disclaimer is listed as
The 64-bit legacy build does not include SSL encryption and lacks
newer features of Windows that enhance performance. Use this build for
Windows Server 2003, 2008, or Windows Vista
The 3.0.5 version is https://fastdl.mongodb.org/win32/mongodb-win32-x86_64-3.0.5.zip
The latest version is available as zip download.
[https://www.mongodb.com/dr/fastdl.mongodb.org/win32/mongodb-win32-x86_64-2008plus-ssl-4.0.6.zip/download][1]
Download and Unzip into folder where user has permissions e.g c:\users\xxx\mongodb.
Enter the path to bin folder (e..g c:\users\xxx\mongodb\bin) into the
environment variable 'PATH'. To access path variable press Win + R
and then enter rundll32 sysdm.cpl,EditEnvironmentVariables.
Select Path and click edit. Then enter new and there enter the path
to bin folder. Click OK and OK to save and exit.
Check Mongo version from command line using command mongo --version.
Note: Don't forget to create db folder in C drive that is required for mongo to work locally. All set.

Could not reserve enough space for object heap with 0.13.1 on Windows?

I installed sbt 0.13.1 from http://www.scala-sbt.org through the msi package.
When I try to start it through a command prompt i get this error
C:\Users\megatron>sbt
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
So I followed the recommendation in the setup notes
and added/changed this in the C:\Program Files (x86)\sbt\conf\sbtconfig.txt file.
-Xmx1536M
-XX:MaxPermSize=256m
-XX:ReservedCodeCacheSize=128m
-Xss1M
-XX:+CMSClassUnloadingEnabled
This doesn't help either and I still get the same error.
It seems you should not have white space characters in the installation path to sbt. You have one in Program Files. Try installing into a different location.
[EDITED, see below]
workaround for me: first try rebooting Windows
I've seen this problem in the past on Windows. Now again with sbt-0.13.5 on Windows 8.1.
By default the sbt installer installs to C:/Program Files (x86)/sbt. I also tried C:/sbt and got the same error while my system appeared to have almost 2G RAM still available. Next, without changing anything else I rebooted and sbt worked from C:/sbt. Then I re-installed using the default C:/Program Files (x86)/sbt path and still sbt works. Of course rebooting isn't a solution.
See related answer. The problem may be that when you are running sbt you are picking up 32-bit JRE (probably via C:/Windows/System32) instead of 64-bit in your path (check with java -version). Apparently the problem is then that although there may be enough memory overall it might not be contiguous that the JVM is requesting.

Eclipse executable launcher error: Unable to locate companion shared library

I had Eclipse Indigo installed on my computer with the Android plugin and it was working perfectly for about two weeks. Today, I updated java and quicktime then restarted my computer. When it booted back up, eclipse had completely vanished - all the program files have completely disappeared. When I try to reinstall it, I get an error message that says
The Eclipse executable launcher was unable to locate its companion shared library.
What happened and how can I fix it?
I've just encountered the same issue. The problem for me was Windows 7 default unzipper program. It has a problem when it encounters files that have a deep file structure. I read about this issue some time ago but can't recall the article. Fix for me is to unzip the Eclipse download using WinZip (or some other tool which does'nt have this issue).
Check eclipse.ini, there are two entries like:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120913-144807
For some twisted reason jars have version in their name - so if you upgrade/have two different version of eclipse( while eclipse.ini is either linked or provided as system wide conf file for eclipse ) it will cause above error.
That sounds pretty bad and weird. But reinstalling isn't that hard - download, unzip, change the default memory allocation, run Eclipse, install necessary plugins and features.
And almost all of the important preferences are in your workspace. The only important one I can think of outside of the workspace is the aforementioned memory allocation, which you can set on the command line or in the ECLIPSE.INI file.
During unzip in a cygwin directory on Win7, .exe and .dll need to be given executable mode. This is the solution from a mintty (or other $TERM) terminal run with cygwin on windows 7:
me#mymachine ~/eclipse
$ find . -name "*.dll" -exec chmod +x {} \;
tried with Juno (eclipse 4.2) freshly unzipped, cygwin 1.7.something
I have seen this in MacOS Sierra. Sometimes unzipping the app leaves extended attributes that seem to prevent the startup. The following command line removes extended attributes and seems to fix the problem:
xattr -c Eclipse.app
It also works for other applications that are built on the eclipse framework.
Another problem (that I ran into) is that Cygwin's unzip utility (UnZip 6.00 of 20 April 2009, by Cygwin. Original by Info-ZIP.) does not always correctly unzip everything needed for Eclipse to actually run.
Using 7ZIP v9.20 got Eclipse Indigo (3.7.2) up and running for me on Win7 64bit with 32bit JVM and 32bit Eclipse.
(First time I've ever had Cygwin's unzip fail on me...)
I just ran into this myself and found that, indeed, as one post above stated: using cygwin and gunzip or unzip to set up your eclipse environment the permissions on the .exe and .dll files will be incorrect and the JVM will not run them properly.
Quick solution:
#switch to the eclipse target folder
cd /cygdrive/c/Program\ Files\ \(x86\) #or wherever you put eclipse
find ./ -regextype posix-extended -mindepth 1 -type f -regex ".*\.exe|.*\.dll" |\
xargs chmod -v 750
I meet this issue after copy a eclipse installation to another pc.I find the eclipse installation auto created the .p2 directory on my c:\Users\xx.p2, and --launcher.library refer to here.So it doesn't exist on my another pc.
My resolution is to reinstall eclipse:
a)Double click eclipse-inst-win64.exe
b)Click to change to advanced mode.
c)Uncheck the Bundle Pool
d)Finish your installation and copy again.Everything will work well.
My experience and advice: Install Eclipse Juno on C: drive.
After download the zip, put it on C:, click the right mouse button -> extract here. Then a folder called eclipse will be created in C: drive.
Then go to Eclipse executable, run it, and all will be ok.
I faced this problem and solved it by running Eclipse as admin.
Problem happened when I unzipped using Cygwin. Used the Windows XP standard unzip program and it worked.
if you are having two eclipse then sometime this happens
you only have to remove
-startup
plugins\org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar
from eclipse.ini file beside eclipse.exe(Launcher)
Also see this related question's answer.
The gist is: Try unzipping it again with a solid unzip tool. Sometimes unzipping goes wrong, especially with the built-in Windows Explorer tool.
i have this error message when i use extract the files as follows:
action\select all
drag and drow the files to an new folder
Somehow information about the folders get lost
when i use "action\extract to..." it works.
Also, remember to right click on eclipse, then choose Security Unblock
Mostly this is related to problems on windows with the unzipping it seems. (See other answers here for that).
The second largest issue seems to be that eclipse is not able to find java or finds a java version which is too old or even older eclipse installations.
Here's another take to the latter problem and a small twist to solve it. My work environment is on a linux system, without root access, and with software installations where I can configure which versions to use in a kind of config file. However I have no influence on the way those software packages are installed and they are immutable to me.
I download and untar the latest eclipse as usual to a user disk for which I have write permissions. Then I configure myself an alias to always temporarily cd into the eclipse installation when starting. That regardless of where I work on the file systems, eclipse always finds its correct libraries. It seems in some places, eclipses default search path for java digs out an installation (of java or older eclipses or sth else) in my environment that it really should not use.
Here's the alias:
alias eclipse '(pushd /enter_path_to_eclipse_install_dir_here/eclipse ; ./eclipse ; popd)'
Now you can start it normally from e.g. your project or arbitrary work directory:
eclipse
Or also put it in the background
eclipse &
Maybe this helps for people in convoluted work environments.
Try running eclipse.exe as administrator or using Eclipse Helios.
I have copied the Eclipse folder from another machine where the path was different and that was the root of this problem. Changing the plugins path in ECLIPSE.INI worked for me !!
Solution for Mac
Reason:
Eclipse copies from one location to other
Solution:
Paths change needed in /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini
Fix path for plugins\org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar
I had the same problem when I was trying to install it on Windows 8.
But it was an zip composed file....
Ones I unzip and Run "eclipes.exe" file as run As 'Administrator' it was resolved.
Now I am enjoying it very well.
I had the same message after a system restore with the eclipse folder (V. 3/2020) being located on a second drive (that was NOT restored at the same time, I use it for large files mainly).
Restoring the faulty installations C:\Users<user>.p2 folder to the new installation (referenced in eclipse.ini of the eclipse folder) worked.
Keep shorter folder name, fixed for me.
I faced this issue recently: (In my case it was installation of STM32CubeMX software):
what I faced: I have two users in my laptop, I had installed the software in one user but on the hard disk partition: D:\
Now I had tried to work on another user!
-- I think you know why I got the error --
So as I was working on the 'other' user account, I got this error every time I tried to compile/build my project - obviously, Because I installed using one user and am working on another.
Workaround: Already mentioned in the above answers clearly!
What I did differently: I tried using the S/W in the other user, but there seems to be issues on the path file/location:
so I reinstalled the location in the user account I want to use and am running it properly now!
Note: While Installing it did ask about installing the software for all user/ current user : I mistakenly had given 'current - user' =(
I also faced ths problem, I just deleted the extracted file and extracted it again.
I have a .rar file.
This problem occurs when the file is not extracted completely.
You might changed your drive-letter:
once u had installed eclipse on D:\, after windows reinstall the drive-letter is now E:\ (for example).
look into eclipse.ini in your eclipse folder, there are some lines where the drive-letter is still D:\
This happened to me when I tried to open eclipse.exe before the .zip file finished extracting. Make sure all dependencies are unzipped or unpacked before opening the .exe.
I had this issue on Linux (CentOS 7 64 bit) with 32-bit Eclipse Neon and 32-bit JRE 8. Non of the answers here or in similar questions were helpful, so I thought it can help someone.
Equinox launcher (eclipse executable) is reading the plugins/ directory and then searches for eclipse_xxxx.so/dll in org.eclipse.equinox.launcher.<os>_<version>/. Typically, the problem is in eclipse.ini pointing to the wrong version of Equinox launcher plugin. But, if the file system uses 64-bit inodes, such as XFS and one of the files gets inode number above 4294967296, then the launcher fails reading the plugins/ directory and this error message pops up. Use ls -li <eclipse>/plugins/ to check the inode numbers.
In my case, moving to another mount with 32-bit inodes resolved the problem.
See: http://www.tcm.phy.cam.ac.uk/sw/inodes64.html
I encountered this error with the Eclipse 4.10 installer. We had failed to complete the install correctly due to platform security settings and attempted to uninstall but had to do it by hand since no uninstaller was introduced during the failed install. We suspected this corrupted the end result - even after re-installing.
The solution was to use the JVM to launch Eclipse and bypass the launcher executable entirely. The following command successfully launches Eclipse 4.10 (some parameters will change based on the version of Eclipse):
%JDK190%\bin\javaw.exe -jar C:\<fully_qualified_path_to_eclipse>\Eclipse410\plugins\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar -clean -showsplash
After using this command/shortcut to launch Eclipse we had no further errors with Eclipse itself but we weren't able to use the EXE launcher in the future. Even after a year of using this version, the launcher continues to display this same error.
To be clear, you'll have to modify your javaw.exe command to match your system specifications on MS Windows.
I got similar error sometime back. I had copied the eclipse setup from another laptop to mine. The issue with my setup was that path of the "--launcher.library" in the eclipse.ini file. The path in --launcher.library was that of the old machine and hence I was getting the error
I changed the path of "--launcher.library" in eclipse.ini to the path of eclipse on my laptop and the issue got resolved. I hope this is helpful to someone is getting this error.
remove it and run eclipse-installer again without root
I have create Demo.exe using Eclipse RCP.
I have run Demo.exe using C-Drive to same error generate like...
Solution : You might changed your drive for example
C:\Demo.exe to D:\Demo.exe
Step 1 : First Copy/Cut your .exe file like C:\Demo.exe
Step 2 : After Paste another drive like D:\Demo.exe
After executable file launching successfully.
I hope my answer is useful.
