Ver Version Java Windows 10
Genciana Haggins
Hi everybody,
I have some trouble with continue using GanttProject because of the license changes of Oracle regarding Java. I am not allowed to use an unlicensed version of a software at my institution, also I am not allowed to use old not updated versions of a software, because of internet security (virus, spam, etc.). Consequently using Java from Oracle is no option for me anymore. Instead I installed an open Java version AdoptOpenJDK ( ). Nevertheless when I start GanttProject it keeps asking me to install the newest Java version before launching.
GanttProject 3.0 will come with bundled Java runtime which will make this process more smooth. Meanwhile, you can try running ganttproject.bat which works with any vendor, provided that java executable is reachable from the user PATH variable (a set of folders where windows searches for executable files). I hope that most vendors put their java.exe into a folder which is registered in PATH.
When I am using openJDK Java in one machine sandbox is working fine .
But when I am using SDK in the machine with java from oracle provider I am getting following error.
Caused by: java.lang.UnsupportedClassVersionError: com/github/blemale/scaffeine/CacheLoaderAdapter has been compiled by a more
recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
The question is not whether or not do you have java.exe installed, it is whether or not do you have a system managed version of it in your C:\WINDOWS\System32. If you do, that takes over the precedence whenever you run the daml assistant and it calls out to execute jars, but does not do when you execute from your interactive session.
When using sonar cloud plugin for azure devops with a hosted agent (win 2019) Machine specs the default (1.8.0) java version is used. But other versions are also installed on the same agent (see machine specs)
This would be a workable solution if you have to maintain a couple of pipelines but in the case of 100+ pipelines then this is not the right solution. On the other hand, by doing this you now depend on a very specific build agent with the given path.
The warning itself is also weird in that the requirements of sonarqube scanner states that it is supported sonar qube requirements and that java 1.8 is still supported until december 2020. I do agree that it would be nice if this warning can be suppressed.
As i do agree that sonarcloud should fix this, I have also created a feature request on the Microsoft side for letting us choose what the default java version should be feature request choosing java version on hosted agend.
Even we are facing the same issue. As of now we have over 25 pipelines. Now for all the Pull Requests this is posted as an warning. Until an action is taken on this, it is stopping the developers from merging the code.
Thank for your feedback. We will have a look on what we can do to improve this. The idea was to really warn the users, and we know that Hosted agent are still stuck on Java 8 by default. Here a summary post that explain the reasons : SonarCloud scanner environment soon to require Java 11+
Short of it is - java used for builds is, in most cases, unrelated to java used for controller/agents. You can use the Tool system to install right versions of JDK as needed. That said, I was under impression that Jenkins did not yet support 17 for running Controller/Agent (you can use it for builds though)
A label can be assigned to an agent. The label can be used the represent the availability of a specific tool version on that agent. Labels could be java8, java11, and java17 to indicate that those Java versions are available on the agent. Labels could be linux, windows, macOS, FreeBSD, or OpenBSD to indicate the operating system hosting the agent. Labels could be git-1.8 or git-2.36 to indicate the specific version of a tool that is installed on the agent.
If your controller is running Java 17, then your agents should run Java 17. Running Java 17 does not prevent you from installing Java 8 and Java 11 (and other Java versions) on the agent. If they are installed, then jobs can use those other Java installations.
This java Path will be used to start the jvm. (/mycustomjdkpath/bin/java ) If empty Jenkins will search java command in the agent
Expressions such as key or key may be declared in the java Path and will be expanded to values of matching keys declared in the list of environment variables of this node, or if not present, in the list of global environment variables.
(from SSH Build Agents plugin)
Environment variables defined here will be made available to every build executed by this agent, and will override any environment variables that have the same Name as those defined on the Configure System page.
Using the syntax $NAME or $NAME (%NAME% on Windows), these variables can be used in job configurations, or from process launched by a build.

Do you need to check if the latest version of Java is installed on your Windows PC? An easy way to see if Java is up to date is to type a quick command at the Windows command prompt. No matter which version of Windows you're using, you can type "java -version" into the command prompt (cmd) to see the version number of your Java installation. This wikiHow article will teach you how to use the command prompt to find out which version of Java (or the Java compiler) is installed on Windows 10, 11, and earlier versions.
The Apache Tomcat software is an open source implementationof theJakarta Servlet,Jakarta Pages,Jakarta Expression Language,Jakarta WebSocket,Jakarta Annotations andJakarta Authenticationspecifications. These specifications are part of theJakarta EE platform.
The Jakarta EE platform is the evolution of the Java EE platform. Tomcat 10and later implement specifications developed as part of Jakarta EE. Tomcat 9 andearlier implement specifications developed as part of Java EE.
The Apache Tomcat software is developed in an open and participatoryenvironment and released under theApache License version 2. TheApache Tomcat project is intended to be a collaboration of the best-of-breeddevelopers from around the world. We invite you to participate in this opendevelopment project. To learn more about getting involved,click here.
Apache Tomcat software powers numerous large-scale, mission-critical webapplications across a diverse range of industries and organizations. Some ofthese users and their stories are listed on thePoweredBywiki page.
Applications that run on Tomcat 9 and earlier will not run on Tomcat 10without changes. Java EE based applications designed for Tomcat 9 and earliermay be placed in the $CATALINA_BASE/webapps-javaee directory andTomcat will automatically convert them to Jakarta EE and copy them to thewebapps directory. This conversion is performed using theApache Tomcatmigration tool for Jakarta EE tool which is also available as a separatedownload for off-line use.
The Apache Tomcat Project is proud to announce the release of version 9.0.90of Apache Tomcat. This release implements specifications that are part of theJava EE 8 platform. The notable changes compared to 9.0.89 include:
Users of Tomcat 10 onwards should be aware that, as a result of the move fromJava EE to Jakarta EE as part of the transfer of Java EE to the EclipseFoundation, the primary package for all implemented APIs has changed fromjavax.* to jakarta.*. This will almost certainlyrequire code changes to enable applications to migrate from Tomcat 9 and earlierto Tomcat 10 and later. Amigrationtool is available to aid this process.
The Apache Tomcat Project is proud to announce the release of version 8.5.100of Apache Tomcat. This release implements specifications that are part of theJava EE 7 platform. The notable changes compared to 8.5.99 include:
The Apache Tomcat Project is proud to announce the release of 1.0.8 of theApache Tomcat Migration Tool for Jakarta EE. This release contains a number ofbug fixes and improvements compared to version 1.0.7.
Version 1.2.5 is a minor bug fix release reverting a change made in 1.2.1 where modified the HTTP method during POST operations, and fixing anissues that resulted in an AccessControlException during startup unlesspermission was granted to read the accessExternalEntity property.
Installing multiple Java versions in parallel is incredibly easy in Windows. You can download and run the installer for each version, which automatically installs the versions in separate directories.
These variables should always point to the same Java installation to avoid inconsistencies. Some programs, such as Eclipse, define the Java version in a separate configuration file (for Eclipse, for example, this is the entry "-vm" in the eclipse.ini file).
The scripts update the JAVA_HOME environment variable and insert the bin directory at the beginning of the Path variable. That makes it the first directory to be searched for the corresponding executable when you run Java commands such as java or javac.
If you have installed the latest releases of all Java versions, you can use the scripts without any further adjustments. Open a new command line or PowerShell and enter, for instance, the following commands:
If one of the commands does not activate the expected Java version, please check if the path in the javaX.bat and javaX.ps1 files corresponds to the installation path of the Java version you want to activate.
