Troubleshooting

Error invalid target release: 1.8 during maven build

If you see this error message during maven build:

[INFO] BUILD FAILURE
...
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project lazyseq:
Fatal error compiling: invalid target release: 1.8 -> [Help 1]

It means you are not compiling using Java 8. Download JDK 8 and let maven use it:

$ export JAVA_HOME=/path/to/jdk8
