Hi! This is the first error:
[INFO] Apache James :: Server :: Common Utilities ......... FAILURE [ 0.659 s] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project james-server-util: Fatal error compiling: invalid flag: --release -> [Help 1] Googling tells me to comment out the “release” flag in maven-compiler-plugin, so I try that (though I don’t understand why) and get a different error: [INFO] Apache James :: Server :: Common Utilities ......... FAILURE [ 0.551 s] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project james-server-util: Fatal error compiling: invalid target release: 11 -> [Help 1] Yeah, that makes sense. I am still on Java 8. So I modify the target.jdk version to 8 and make a bit of progress: [INFO] Apache James :: Core Domain Objects ................ FAILURE [ 0.597 s] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project james-core: Compilation failure: Compilation failure: [ERROR] /Users/dleangen/libs/james-project/core/src/main/java/org/apache/james/core/builder/MimeMessageBuilder.java:[400,46] no suitable method found for toArray(InternetAd[...]::new) Hmmmm. This is in the code. I just want to compile, not debug at this point. This makes me think that the project is currently being neglected. :-( Ok, let me try to omit the core project (though that does not sound like a promising approach). [INFO] Apache James Cassandra backend ..................... FAILURE [ 18.471 s] [ERROR] Failed to execute goal on project apache-james-backends-cassandra: Could not resolve dependencies for project org.apache.james:apache-james-backends-cassandra:jar:3.6.0-SNAPSHOT: Could not find artifact org.apache.james:james-core:jar:3.6.0-SNAPSHOT in apache.snapshots (https://repository.apache.org/snapshots) -> [Help 1] Yeah, like I expected. Ok, so try mvn eclipse:eclipse without building the project, then? I only get this far: [INFO] Apache James :: Test helpers for Mailet ............ FAILURE [ 1.859 s] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-remote-resources-plugin:1.6.0:process (process-resource-bundles) on project apache-mailet-test: Execution process-resource-bundles of goal org.apache.maven.plugins:maven-remote-resources-plugin:1.6.0:process failed: Failed to resolve dependencies for one or more projects in the reactor. Reason: Missing: [ERROR] 1) org.apache.james:james-core:jar:3.6.0-SNAPSHOT [ERROR] 2) org.apache.james:apache-james-mailbox-api:jar:3.6.0-SNAPSHOT Perhaps only a simple fix is required to get everything compiling, but since I have never yet looked at any of the code base, I don’t know. I can’t even set it up in my Eclipse yet because I cannot run mvn eclipse:eclipse until I can get the projects to compile. I’m sure someone with enough motivation could figure out a way around these issues, but I thought that the golden rule was that the project should compile out of the box. That’s why I asked my original question.
