Question

Where to get tools.jar for Java 8 JDK early release? Without it, my Java 1.8 Maven pom based projects in Netbeans will not compile.

The Java 8 early release is set in

Answer 1

You just need to install devel package. On RHEL family it's like this:

# yum install java-1.8.0-openjdk-devel

Answer 2

The tools.jar file on the 1.8.0 JDK is located in jdk1.8.0/lib/tools.jar. If it's not there, then you don't have the JDK installed correctly.

Answer 3

Make sure you look into the folder C:/Program Files/Java/jdk1.8.0_version/lib instead of C:/Program Files (x86)/Java/jdk1.8.0_version/lib

Answer 4

1. Install the latest JDK from here.

2. If the problem not solved then go back to react-native documentation about installing react native (android) on mac, here

3. In root of your reactnative project :

    cd android
    ./gradlew clean 
    ./gradlew assembleRelease

Answer 5

Some JDK packages contain just the Java Runtime Environment.

So for instance in Fedora, Oracle Linux, RHEL, CentOS java-1.8.0-openjdk package contains just the JRE. If you want the development tools, then install the java-1.8.0-openjdk-devel package instead.

And in Debian/Ubuntu openjdk-8-jre package contains just the JRE. If you want the development tools, then install the openjdk-8-jdk package instead.

Answer 6

Simply, copy the tools.jar from your jdk\lib folder and paste into jre\lib folder.
