Angular project facing issues during Maven build process

Hi there, I'm currently facing some challenges while trying to deploy my Angular and Spring Boot application. Whenever I run the command 

mvn clean compile spring-boot:run
, I encounter a build failure from my Angular pom file.

The error message I am receiving is as follows:

C:\work\projects\todo>mvn clean compile -e
[INFO] Error stacktraces are turned on.
...
(ERROR DETAILS GO HERE)
...
[ERROR]
[INFO] ------------------------------------------------------------------------
[INFO] Reactor Summary for todolist-parent 0.0.1-SNAPSHOT:
[INFO]
[INFO] todolist-parent .................................... SUCCESS [  0.921 s]
[INFO] todolist-web ....................................... FAILURE [ 32.761 s]
[INFO] todo ............................................... SKIPPED
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

After analyzing the error log, it seems that the main issue revolves around this particular line:

[INFO] ERROR in C:/work/projects/todo/todolist-web/src/main/web/node/node_modules/npm/node_modules/smart-buffer/typings/utils.d.ts (2,29): File 'C:/work/projects/todo/todolist-web/src/main/web/node/node_modules/npm/node_modules/smart-buffer/typings/smartbuffer.d.ts' is not being recognized as a module.

This generated file seems to be causing some confusion. However, I am unsure about how to rectify this issue or what exactly it entails. Could you please provide guidance on how to resolve this?

Answer №1

After doing some research, I was able to identify the root of the problem. It appears that we must exclude the node folder from the tsconfig.json file, as it is generated by the com.github.eirslett's frontend-maven-plugin plugin during the building process. The TypeScript compiler was mistakenly including the contents of the node folder in the compilation.

Give this code snippet a try -

{
    "compilerOptions": {
        "module": "system",
        "noImplicitAny": true,
        "removeComments": true,
        "preserveConstEnums": true,
        "outFile": "../../built/local/tsc.js",
        "sourceMap": true
    },
    "include": [
        "src/**/*"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts",
        "node"
    ]
}
