Errors building from maven
summitt opened this issue · 3 comments
I'm having some issues building the project using mvn package. First i was getting this error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project mallet: Fatal error compiling: invalid flag: --release -> [Help 1]
Then I removed the <release/> line from the pom.xml file and I got a little further. Now i'm getting several errors like this:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project mallet: Compilation failure: Compilation failure:
[ERROR] /Users/josh/tools/mallet/src/main/java/com/sensepost/mallet/swing/editors/ReflectionEditor.java:[122,56] diamond operator is not supported in -source 1.6

Below are the versions i'm using:

Hey Josh. I guess I have something wrong with the pom, that it is not setting the right source levels (Java compatibility levels) somehow.
Could you please try setting the <source> and <target> elements to 1.8, as shown here: https://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html
Perfect! That fixed it. Thanks @RoganDawes
Awesome! Did you remove the <release>11</release> element? Or did it work with both in place? Then I can update the pom, and commit.
