Vim YouCompleteMe Java setup

I'm trying to set up Java autocompletion for Vim using the YouCompleteMe plugin. I ran the install script and got the following message saying that I need to set an option called java_binary_path:
$ python3 install.py --java-completer --clang-completer
Generating ycmd build configuration...OK
Compiling ycmd target: ycm_core...OK
Building regex module...OK
Building watchdog module...OK
Installing jdt.ls for Java support...
*** WARNING ***: jdt.ls requires Java 17. You must set the option java_binary_path to point to a working java 17.
OK
I tried setting this in my ~/.vimrc file as follows, but now I'm getting the error E518: Unknown option: java_binary_path=/usr/local/opt/openjdk#17/bin/java:
set java_binary_path=/usr/local/opt/openjdk#17/bin/java
Does anyone know how to set this option?

CERTIFICATE_VERIFY_FAILED when trying to build java-cef

I'm trying to build java-cef on ubuntu following instructions from https://bitbucket.org/chromiumembedded/java-cef/wiki/BranchesAndBuilding.
At cmake step
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ..
i get
-- Downloading clang-format from Google Storage...
Failed to fetch file gs://chromium-clang-format/942fc8b1789144b8071d3fc03ff0fcbe1cf81ac8 for tools/buildtools/linux64/clang-format.

]
Terminal indicates that I'm using Python 2.7.15+.
How can i make it work? Many thanks.

In the folder where it has created the build jcef/src/tools/buildtools/download_from_google_storage.py change the version parameter of gsutil to a recent version, like 4.39. If you don't find specified file use a tool like find.

Ionic Android build stopped working

My Ionic/Cordova app has all of a sudden stopped building on Android after updating the Ionic and Cordova CLI. I've spent the last 2 days searching Google for a solution but I couldn't find anything that has helped. I'm assuming it's something to do with Cordova now using Gradle to build instead of Apache Ant. My Android SDK and build tools are all up to version 22, Gradle 2.2, Ant 1.9.4, JDK 8.
Other details:
Cordova CLI: 5.1.1
Ionic CLI Version: 1.6.1
Ionic App Lib Version: 0.3.3
OS: Mac OS X Yosemite
Node Version: v0.12.7
When I run ionic build android, I get this error:
FAILURE: Build failed with an exception.

You might need to set the android-versionCode in your config.xml file. I had a similar issue that was resolved by changing the code from "0.0.1" to "1". Apparently Android wants a single integer value.
In my config.xml I had to change this:
<widget id="com.acme.appname" version="0.0.1" android-versionCode="0.0.1" ios-CFBundleVersion="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
to this:
<widget id="com.acme.appname" version="0.0.1" android-versionCode="1" ios-CFBundleVersion="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
android-versionCode
I hope this helps.

Building phone gap app for Android failing

I tried setting the java_home to the java alias in lib exec but still nothing. Any ideas on what maybe causing the problem?

It's because your InAppBrowser plugin is out date and probably out of sync with a newer version of the Cordova Android platform than when you first installed the plugin. I was getting the same issue with cordova-android#4.0.0 and 0.5.3 of InAppBrowser.
Fix is to first remove plugin
cordova plugin rm org.apache.cordova.inappbrowser
Then add it again (it should reinstall with the latest version the cordova CLI has in my case it grabbed 0.6). You can check the version in the RELEASENOTES.md in the plugins/org.apache.cordova.inappbrowser/ folder.
cordova plugin add org.apache.cordova.inappbrowser
You will need to remove the android platform and re-add it before building again so it doesn't keep the old version of the plugin.
cordova platform rm android
and
cordova platform add android
Now build again and the error should have gone.
EDIT: I just noticed at the top of your question you are using phonegap. Since you tagged with cordova (and thats what I use) I answered with cordova commands, but I'm guessing almost the same process applies with Phonegap.

Same problem with cordova-android#4.0.0
Thank's JDawgg your solution's better than mine, but if someone still have the bug you can use cordova-android#3.6.4 like this :
cordova platform remove android
then
cordova platform add android#3.6.4
you must have android 4.2.2 sdk installed
Finally
sudo phonegap build android

In case someone is using Meteor and came across the same problem, martijnwalraven suggests removing the older version of cordova-plugin-inappbrowser and add the most recent one:
$ meteor remove cordova:cordova-plugin-inappbrowser
$ meteor add cordova:cordova-plugin-inappbrowser#1.0.1
This did the trick for me!

Could not find file mysql-connector-java-5.1.13-bin.jar

Hi when i try to run sakila database example from netbeans site
https://netbeans.org/projects/samples/downloads/download/Samples/JavaEE/DVDStoreEE6.zip
i have some problem showing following in my n output windows
of NetBeans 7.3.Beta2
ant -f "C:\\Users\\unknown\\Documents\\DVDStoreEE6 (1)"
-DforceRedeploy=false -Ddirectory.deployment.supported=true -Dnb.wait.for.caches=true run init: deps-module-jar: deps-ear-jar: deps-jar: library-inclusion-in-archive: C:\Users\unknown\Documents\DVDStoreEE6 (1)\nbproject\build-impl.xml:995: Warning: Could not find file C:\Applications\NetBeans\NetBeans Dev
201107270600.app\Contents\Resources\NetBeans\ide\modules\ext\mysql-connector-java-5.1.13-bin.jar to copy. BUILD FAILED (total time: 0 seconds)
Can any one guide me why this problem is occurring?

You need to download mysql-connector-java-5.1.13-bin.jar and then set your classpath.
here the link to download

In case if you have already included the 'mysql-connector-java' jar file and are still facing the same error like me, here is what you can do.
When the error is displayed in the output window click on the blue link that is displayed.
Eg:
C:\Users\Username\NetbeansProjects\ProjectName\nbproject\build-impl.xml
Within that remove the below line,
<copyfiles files="${file.reference.org-netbeans-modules-db-mysql.jar}" todir="${build.web.dir}/WEB-INF/lib"/>
Hope this helps.
