Cannot perform mvn clean install

Ask OpenMRS
1

Hi all,

I’m pretty new with all open source. I had recently started exploring what OpenMRS does and all. Right now, I’m setting up the environment.

I had cloned the git repo of openmrs-core from : https://github.com/openmrs/openmrs-core I followed the instructions given in the manual and have set up the eclipse ide and required tools.

But when I try to perform mvn clean install, I’m constantly facing this issue

  1. Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.1:compile
  2. \api\src\main\java\org\openmrs\ObsPostLoadEventListener.java:[14,23] error: package javax.annotation does not exist

I tried the quick fix suggested for 1 from the manual - installing “Maven Integration for Eclipse” from eclipse marketplace. I don’t understand the second because if I try to add a new dependency which it says missing then it gives many more errors.

Thanks in advance! https://pastebin.com/vcj4JNAp

Dear Daniel,

I am getting exactly same error as asked in the question. Pretty new to OpenMRS and trying to setup the environment. Earlier I had JDK14 then I downgraded to 8 I suppose, following version info

java version “1.8.0_241” Java™ SE Runtime Environment (build 1.8.0_241-b07) Java HotSpot™ 64-Bit Server VM (build 25.241-b07, mixed mode)

Still am getting the error. Is above java version ok?

Also, I followed this - https://wiki.openmrs.org/display/docs/User+Interface+Modules ( For Developers section)

Best Regards, Supriya

It should be. What’s the output of mvn -v?

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) Maven home: D:\MedicalProj\apache-maven-3.6.3\bin… Java version: 1.8.0_241, vendor: Oracle Corporation, runtime: D:\MedicalProj\Java1.8 Default locale: en_US, platform encoding: Cp1252 OS name: “windows 10”, version: “10.0”, arch: “amd64”, family: “windows”

Can you use pastebin.com to paste the output that happens when you run mvn clean install?

Sorry , I restarted my tablet to see if something works, and now it gives me below diff error, I will try pastebin now -

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.1:compile (default-cli) on project openmrs-api: Compilation failure

[ERROR] Unable to locate the Javac Compiler in:

[ERROR] Please ensure you are using JDK 1.4 or above and

I will check tools.jar fix too.

Thank you for your time n help!

@supriyat It’s exactly like the error says: you need to have the Java 8 JDK installed, not just the JRE.

I’m using Eclipse 2022-03 which includes/requires Java 14. Do I have to maven compile from command line, and make sure maven uses a JDK 8? It’s very inconvenient.

With platform 2.4 you can use java 14 as per the release notes on this link OpenMRS Platform 2.4.0 Released

Thanks, currently I’m just trying to compile openmrs-core
