Error starting build apache solr. How to fix?

I forked this apache solr and when I try to build as indicated in the README, I get the following errors:
When trying to install on java version 11
[root#192 solr]# ./gradlew assemble
Exception in thread "main" java.lang.IllegalArgumentException: error: release version 11 not supported

\nSomething went wrong. Make sure you're using Java 11 or later.
Then I decided to change the version to 1.8.0, having received the following:
[root#192 solr]# ./gradlew assemble
Unrecognized option: --source
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
\nSomething went wrong. Make sure you're using Java 11 or later.
Has anyone encountered the same problem, and if you managed to solve it, then how?

Why do i get Forbidden <403> error while trying to start Grails 3+ on windows?

I am trying to do a project using Grails and I'm really new to this subject.
I also searched and there's another similar question without a proper answer.
Anyway, I installed Grails both 3.2.9 and 3.3.0 M1 versions:
C:\Users\acer>grails -version
| Grails Version: 3.2.9
| Groovy Version: 2.4.10
| JVM Version: 1.8.0_102
And I'm getting the same Error when I'm trying to create an application.

It's really important for my project
I apreciate any help or suggestion in advance

This looks like it's happening during dependency resolution. Those dependencies would likely be first coming from https://repo.grails.org/grails/core/, as found in build.gradle, if you could get an app created. It looks like you're maybe having trouble accessing that repository. Confirm you can access that URL from your machine and try again.

You system is actually identify Grails Version: 3.2.9
It happens for project build issue. You need to rebuild your project by running this command
grails clean

ElasticSearch java.lang.IllegalStateException: jar hell

I was able to run my application previously but since today when i tried some experiments it gives me jar hell error out of sudden. Which I have no idea what this exception about, and now my project couldn't work anymore. This is the error causes:
44 [main] DEBUG org.elasticsearch.bootstrap - examining jar: /usr/local/apache-tomcat-7.0.62/lib/annotations-api.jar

Why is the jar hell occurring? I never seen this before in my developer life and my application was workable before today. Am I missing something important to implement elasticsearch? Here is my code snippet.
Settings.Builder settings = Settings.settingsBuilder();
settings.put("path.home", Paths.get("").toAbsolutePath().toString() + File.separator + "resource" + File.separator + "elasticsearch-2.1.2");
settings.put("cluster.name","mySearch");
Node node = NodeBuilder.nodeBuilder().settings(settings).build().start();
Client client = node.client();
Any helps or clues are welcome and greatly appreciate
EDIT 1:
I was not using VM argument to determine the ES home path as I need to take the project into different paths and platforms when I transferring project.
EDIT 2:
I tried to change my project with elastic home path in VM argument also won't work anymore because I did following the solution that mentioned with this link, but error still raise.

Try to use:
-Dtests.jarhell.check=false
Remark: It works with my Elasticsearch 2.4. I saw comments, that it is not available in all Elasticsearch versions (see Elasticsearch jar hell when writing integration tests)

I got the same error message with catalina.jar conflicting with catalina-ant.jar. So, the quick fix was to rename catalina-ant.jar to catalina-ant.jar.orig in the $TOMCAT/lib folder.
Tomcat is still running for me, even with the one library missing.

Build Failed in Liferay 6.2

I am getting Build Failed, while deploying the Portlets,Themes and Layouts in liferay 6.2 on ubuntu OS .
The console messages are:
The Build Failed Message on Console:
BUILD FAILED
/opt/scrum-6.2/plugins/layouttpl/20x80-layouttpl/build.xml:7: The following error occurred while executing this line:
/opt/scrum-6.2/plugins/layouttpl/build-common-layouttpl.xml:5: The following error occurred while executing this line:
/opt/scrum-6.2/plugins/build-common-plugin.xml:5: The following error occurred while executing this line:
/opt/scrum-6.2/plugins/build-common.xml:47: The following error occurred while executing this line:
/opt/scrum-6.2/plugins/build-common-ivy.xml:17: The specified destination is a directory
Can any one help me?

Solution -> Edit build-common-ivy.xml and change line 17 so that it looks like this:
dest="${ivy.home}/ivy-${ivy.version}.jar"
Also, it complains that you need Ant 1.8, so be sure to upgrade to 1.8.

I have resolved the build failed issue
The following file is missing in plugins:
---> build.username.properties file
And inside the .ivy folder,cache folder and ivy-2.3.0.jar files are missed.
I just have added the above things in plugins.

Bootrun error when trying to run grails

I was setting up to run graddle from my terminal using "grails dev run-app" command, then an error occurred.
I'm not sure what causing the error, but what I have installed are:
Java JDK 1.8.0_111
Grails 3.0.14
MySQL
I have tried to use "grails clean" and try to use "export=JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home'" but still outputs the same error.
This is the simplified long error:

Deeply thanks for anyone who could provide a solution to this matter.

The warning message Running application... Which one is undefined is not matter. I think your failure cause by wrong password for 'mobileeyeclinic'#'localhost' or may be the MySQL is not running as a service. See this link Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined for more info
