I am working on using Floodlight Controller for SDN. I used
ant eclipse
to setup the Eclipse files and then changed the Build Configuration as desired in the installation instructions. I am getting the following compilation error in the package net.floodlightcontroller.util.MatchUtils:
The method setMasked(MatchField<F>, Masked<F>) in the type Match.Builder is not applicable for the arguments (MatchField, Masked)
on lines 141 and 148.
Can somebody help me with the issue?
Operating System: Mac OS X 10.10
Java Version:
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
As suggested in the comments above, it works with Java SE 1.7. There is also a Github Issue.

I have just downloaded Eclipse and tried to run it, and it gave me this error message:
Error: opening registry key 'Software\JavaSoft\Java Runtime Environment
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.
After closing the errors, it sends me to this site:
https://download.eclipse.org/oomph/jre/?vm=1_1_8_0_64_0&pn=Eclipse%20Installer&pu=http://wiki.eclipse.org/Eclipse_Installer&pi=http://download.eclipse.org/oomph/jre/128x128.png
I have already reinstalled the jdk multiple times.
After following some other posts i saw, i have also made sure that %JAVA_HOME% was included in PATH
(%JAVA_HOME% = C:\Program Files\Java\jdk-13.0.1)
to java -version i got:
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
Thank you in advance for the help!
Edit:
I had both jdk-13.0.1 and jre 1.8.0 installed
After reinstalling only jdk 13.0.1 (and uninstalling jre 1.8.0), java -version gave me:
java version "13.0.1" 2019-10-15
Java(TM) SE Runtime Environment (build 13.0.1+9)
Java HotSpot(TM) 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)
I'm using Windows 10 Pro

According to this answer maybe you messed up with your registry, make sure all java removed first and reinstall JRE.
For me if I want to develop java apps, I would install JDK instead of JRE, after install pls check java & javac command exist

One thing I noticed is the JAVA_HOME path refers to JDK 13, while the "java -version" command points to 1.8. Specify the version of Windows and Eclipse you have used in this question. Also, make sure you restart the PC after installing Java. – Shankar P S 52 mins ago

I try to understand why do I have Java 11 in Intellij. When I run the java -version in Intellij terminal I get this response:
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+12-b304.10)
OpenJDK 64-Bit Server VM (build 11.0.3+12-b304.10, mixed mode, sharing)
When I run the same command from Windows command prompt I get this:
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
I really don't understand why I have Java 11 in Intellij terminal because I have these Project settings:
Modules:
Java Compiler:
And in the pom.xml:
<properties>
<java.version>1.8</java.version>
</properties>
So why do I have Java 11? I want to use Java 8. Any feedback will be appreciated.
The shell running in IDEA inherits its environment from IDEA. IDEA is itself a Java program, so whatever script or stub program started its JVM probably set the PATH so that it picks up the version 11 JDK that was installed with IDEA. When you do java -version in the IDEA shell, you get IDEA's version. But outside of IDEA, the version you get is determined by the PATH you set up in your Windows environment.
I have downloaded the elesticsearch on the CentOS 7 server.
This server has the following version of java:
openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-b16)
OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)
When I run the bin/elasticsearch it fails with the following error:
Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker
Elasticsearch requires at least Java 8 but your Java version from /bin/java does not meet this requirement
As you can see It says that it can't find the java 8.However the java -version indicates the current java version is 1.8.
I have tried a lot but can't solve this.
Please help me.
I build a dll with Visual Studio 2008 and it's called by java side throuth jni.
It works fine in A machine but failed in B machine.
The error info is like:
java.lang.UnsatisfiedLinkError:xxx.dll Can't find dependent libraries
The configuration info is like below (The OS and jdk is the same):
A machine:
Win7 64bit;
java version "1.7.0_21" Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) Client VM (build 24.71-b01, mixed mode, sharing)
eclipse-standard-kepler-SR2-win32-x86_64
B machine:
Win7 64bit;
java version "1.7.0_65" Java(TM) SE Runtime Environment (build 1.7.0_65-b19)
Java HotSpot(TM) Client VM (build 24.71-b01, mixed mode, sharing)
eclipse-java-luna-SR1a-win32
The code generation of dll is Multi-threaded Debug (/MTd).
I have no idea about the cause so that please let me know if you need more information to judge the cause.
Thanks for your help in advance.
To find the missed dependency use the Dependency Walker. Open your DDL and it will show you all DDLs it depends on. It will show you also which one could not be found on the current systen.
http://www.dependencywalker.com/
The java.lang.UnsatisfiedLinkError:xxx.dll Can't find dependent libraries is throwed in B machine but not in A machine is because that dll's dependent libraries can't be found by the dll in B machine and to fix it, you can add dependent libraries' path to the environment path. To get the dependent libraries, follow #SubOptimal's suggestion.
I have problem to use maven from ubuntu server 13.10 64bit.
I am getting following error (even when I type mvn -version):
Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/lib/jvm/jdk//bin/java
But when I type java -version I get:
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
I have no idea where can be the problem, especially because I have used maven without any problems before I've installed hadoop 2.2.
Thank you in advance for any help.
It appears that the Hadoop instructions and/or start up script modifies the JAVA_HOME environment variable in the shell.
Unless this change is made permanent by changing one of the many configuration files - like $HOME/.profile - it only influences the shell in which you have observed the problem.
