+# DEVELOPER INSTALLATION SCRIPT

+# You must have Java Development Kit (JDK) 8 (1.8). If higher (>8) then it must
+# support --release flag to pin down the version when compiling.
+# Always compile with 8 (1.8) to keep backward compatibility.
+# In conda, you can get a JDK version that supports --release flag:
+# conda install openjdk
+javac --version &&  # java version
+javac -cp src/accelerometer/java/JTransforms-3.1-with-dependencies.jar src/accelerometer/java/*.java --release 8 &&  # compile java files (using release 8)
+pip install -e .[dev,docs] # install in edit mode
