Cannot perform mvn clean install

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

Downgrade to Java 8 and compile again.

Thank you @dkayiwa @jnsereko I have downgraded to java 8 and it builds successfully :+1: without any errors.

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

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.

Dear Ian, Got the right JDK downloaded again n reinstalled it. Build successful! yet to explore OpenMRS further. Thanks a lot again! Best Regards, Supriya
