 These instructions are meant for developers interested in working on the IGV code.  For normal use,
 we recommend the pre-built releases available at [http://software.broadinstitute.org/software/igv/download](http://software.broadinstitute.org/software/igv/download).

 Builds are executed from the IGV project directory.  Files will be created in the 'build' subdirectory.
-You may need to execute 'gradle wrapper' to set up the gradle wrapper.  This should be necessary the 
-first time only, or if you clean up the local .gradle directory.  Only do this if the './gradlew' calls
-fail.

-There are two different build options, one for Java 8 and another for Java 11.  The default is 
-to build for Java 8.  Java 8 builds are *NOT* compatible with Java 11 and vice versa.

-#### Java 11
-
-The instructions for Java 11 are nearly identical other than the need to specify the Java 11 build file
-and that the results will be found in 'build_java11' rather than 'build'.  More specifically:
-
-* Use ```./gradlew -b build_java11.gradle createDist``` to build a distribution directory with helper scripts
-  for launching.  The structure is slightly different but the concept is the same.
-
-* Use ```./gradlew -b build_java11.gradle test``` to run the test suite.
-
-The full JAR build option is *NOT* available for Java 11 because of modularity requirements.  Also, there is no 
-separate igvtools distribution on Java 11; at present, this is folded into the normal IGV client distribution.
