"Nios II software build tools for eclipse" is not openning

Question

I have Quartus-lite-17.1.0.590 installed on Debian Stretch. When I try to open the nios ii software build tools for eclipse from Tools menu,

the eclipse start screen appear,

then a empty window appear,

and the messages pops up saying that the Nios II - eclipse is not responding.

I tried waiting for sometime but it didn't work

Is there anyone having this issue or are there any fixes?

FYI - I installed Quartus and ModelSim in unattended mode

Hi, I found the solution in this forum:
https://www.eevblog.com/forum/fpga/quartus-issue-nios-2-software-build-tools-for-eclipse-crashes-on-startup/
the problem was solved by following the document from "Intel": https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2019/why-does-the-nios--ii-not-installed-after-full-installation-of-t.htmlThe same instructions also included in the &lt;Intel Quartus installation directory&gt;/nios2eds/bin/README
these are the instructions that you will find for Quartus 20.1 lite 
QUARTUS ECLIPSE MANUAL INSTALLATION1. Download CDT 8.8.1 which is Eclipse C/C++ IDE for Mars.2a. Windows: https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/mars/2/eclipse-cpp-mars-2-win32-x86_64.zipb. Linux: https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/mars/2/eclipse-cpp-mars-2-linux-gtk-x86_64.tar.gz2. Extract the downloaded file into &lt;Quartus installation directory&gt;/nios2eds/bin. You should see &lt;Quartus installation directory&gt;/nios2eds/bin/eclipse folder after extraction is done.3. Rename &lt;Quartus installation directory&gt;/nios2eds/bin/eclipse folder to &lt;Quartus installation directory&gt;/nios2eds/bin/eclipse_nios24. Extract &lt;Quartus installation directory&gt;/nios2eds/bin/eclipse_nios2_plugins.zip (or tar.gz for Linux) to &lt;Quartus installation directory&gt;/nios2eds/bin. The extraction will override files in &lt;Quartus installation directory&gt;/nios2eds/bin/eclipse_nios2. 5. Verify the extraction is done correctly by making sure you see &lt;Quartus installation directory&gt;/nios2eds/bin/eclipse_nios2/plugin_customization.ini file6. You can now launch Nios2 II SBT for Eclipse via eclipse-nios2.exe
