The new modular build has been committed to 9-dev !!!
To ensure a continued happy development, please consider the following advice :-) Clean up your old repository before syncing. gradle clean consider (but not required) hg purge --all unset JIGSAW_HOME # this enviroment variable is no longer used in 9-dev Download, install and verify you have the version you think you have. Gradle 3.1+ [1] JDK 9 build 142+ [2] Ant 1.8.2 (note, that there are known issue with 1.9.x) [3] Remember, if you still need to work with older workspaces like 8, keep gradle 2.11 around, as Gradle 3.1 will NOT work. To help with this, I set to environment variables: GRADLE2_HOME=__path_to_gradle_2 GRADLE3_HOME=__path_to_gradle_3 and then now add $GRADLE3_HOME/bin to my path as this is the default I use. But this allows me to use $GRADLE2_HOME/bin/gradle in older repositories. At this point, sync in the new changes and build it ! export JDK_HOME=_path_to_jdk_9_ea_142+ $GRADLE3_HOME/bin/gradle clean sdk [1] https://gradle.org/gradle-download/ [2] https://jdk9.java.net/download/ [3] https://ant.apache.org/bindownload.cgi -- David Hill<david.h...@oracle.com> Java Embedded Development "A man's feet should be planted in his country, but his eyes should survey the world." -- George Santayana (1863 - 1952)
