This is my first time to try maven. My os in linuxmint.I have install maven successful.
mvn -v

But when I have used mvn archetype:create
mvn archetype:create -DgroupId=org.sonatype.mavenbook.ch03 -DartifactId=simple -DpackageName=org.sonatype.mavenbook
it showed a strange error.
[WARNING] Error injecting: org.sonatype.plexus.components.cipher.DefaultPlexusCipher
com.google.inject.ProvisionException: Unable to provision, see the following errors:Error injecting constructor, org.sonatype.plexus.components.cipher.PlexusCipherException: java.security.NoSuchAlgorithmException: SHA-256 MessageDigest not available

while locating org.sonatype.plexus.components.cipher.DefaultPlexusCipher
It was so strange, how should I do?
I think maybe you have already figured your problem. But I got this bug yesterday and I fixed it today. I should write my solution down. Maybe someone will fall this trap.
Actually this problem is because Java cannot find the class "SHA-256 MessageDigest". But it is provided by JRE default. It should be found automatically.
If you access your JAVA_HOME, you may find a file whose name is jsse.pack in JAVA_HOME/jre/lib, and there is not a file named jsse.jar. That is the problem. Type
unpack200 jsse.pack jsse.jar
(unpack200 will be recognized as soon as you have set your Java path)
and the problem should be soloved.
Note:
Some JDK's have jsse.rar not jsse.pack, therefore, running "unpack200 jsse.rar jsse.jar" command will get the desired result, and will not delete the "jsse.rar" file (in case of *.pack files, they get replaced by the *.jar files).

I've prepared docker image that demonstrate the problem:
https://drive.google.com/uc?id=1i04_dVL0Rp5rxXCMuHaS4LYREkZjAAW1&export=download
This image is basically alpine:3.11 + apk add openjdk8 maven + my maven project containing sample minimal java class that shows problem
Which you can try with following commands:
# docker load -i bugexample.img
# docker run -w /root/bug-example --name bugtest bugexample /bin/ash build-until-sha-different.sh
If you are lucky enough (sometimes require several attempts) you will get following output:
Found! Sha1 of two subsequent otherwise identical builds are different!

+6a303d69d3f382b23ca04caee4102ee1cd7151e3 com/SimpleBug.class
The core issue with this build is that it produce different bytecode almost each time it get build even though nothing else (neither environment, nor code itself) had changed.
When I do compare these different class files I see that they differ in one single byte:
# cmp -lb 1_SimpleBug.class 2_SimpleBug.class
4053 66 6 65 5
Digging deeper into class file structure I've found that this difference come from stackmapframe constant pool pointers (StackMapTable attribute -> stack_map_frame entry with tag Object_variable_info -> cpool_index)
1_SimpleBug.class
#35 = Utf8 supSetStringParameter10
#36 = Utf8 Lcom/google/common/base/Supplier;
2_SimpleBug.class
#35 = Utf8 supSetStringParameter10
#36 = Utf8 Lcom/google/common/base/Supplier;
So one file points to #35 and another to #36. I don't think this is correct behavior.
I would like to sumbit this to a proper issue tracker but I don't know how to do that since all related JDK trackers are for devs only.

Well... The Mountain in Labour...
All of this was for nothing. Maven was main culprit. First time I ran my build it downloads lots of stuff that maven require (apart from my project dependencies) and then start compilation in same jvm. Second time build runs there is no need to download so compilation starts immediately. I don't know exactly why but first invocation of compiler is somehow affected by state of the jvm and this cause it to produce slightly different bytecode.
Solution was to add <fork>true<fork> to my pom.xml file and build now is totally reproducible... though takes ~2x more time :)
I still believe that this should not happen even if initial compilation happened inside maven jvm, and it may still be topic for improvement in javac but this "workaround" is acceptable.

In general, like #Ittai, I would suggest you open an issue in the intellij plugin github repo.
Unfortunately, your version of the plugin is no longer supported. I, too, previously ran into an issue with an older version of the plugin and was recommended to upgrade to the latest version. Which resolved the specific issue I was facing.
When reporting the issue make sure to include the following bits of information:
intellij build number
plugin version number
rules_scala version
operating system (it seems your using Windows, while most users use unix based systems)
bazel release number
how you have opened the intellij project (BUILD file, WORKSPACE, .blazeproject)
Additionally, to verify this is in fact an issue with the plugin, I would also suggest you try to reproduce this issue on a Unix based system. It seems you are using Intellij
compile on Windows. This may be Windows specific issue with aspects not being recognized.
When attempting to reproduce, make sure to clone your repository in a separate directory, close the intellij project, and reopen the project
I've just used homebrew to successfully install the latest neo4j (Community Edition 2.1.4) on my MacBook Pro - however, I've been unable to get the server to start.
My question seems similar to this though that question remains unresolved (and the suggestions haven't worked for me).
Just quickly: I have previously successfully installed and booted the trial of the Enterprise Edition (over a year ago) and I've since removed it. Pure speculation but I'm guessing that my issues could be related to this.
When I run neo4j start
I get

It seems conf/log4j.properties isn't created at all. I've then copied the contents of that file from my brothers successful installation which seems to remedy the first error though the second error persists with the same result when I try to start the server again.
I've also tried to install via direct download and get the same result.

I've had some success – or, at least, I've got neo4j working now on my machine.
Following the suggestion in this google thread I removed slf4j-api-1.5.8.jar and slf4j-log4j12-1.5.8.jar from /Library/Java/Extensions and the server now boots.
I have no idea if this will have unexpected negative consequences but it definitely seems to solve my problem. Moving on.

How can I overcome this.
Finally I got it,why I am getting this problem 'cmd' is not recognized as an internal or external command, operable program or batch file. Because the following path C:\Windows\System32 was not set in Environment variables. I found through google.I fix it.run same command again it doesn't show any error.
