Làm thế nào tôi có thể tăng tốc quá trình xây dựng bằng cách sử dụng công cụ maven

Question

Tôi đang sử dụng maven làm công cụ xây dựng. Hiện nay tôi đang làm xây dựng như là làm theo

Right click on the project - >maven clean. 

Sau này

Right click on the project - >maven install 

Nó đang tiến hành 3 phút cho me.Is Có cách nào để tăng tốc độ quá trình của tôi

Tôi đã thấy this. Nhưng tôi không hiểu điều này. Có ai có thể gây hại cho tôi không?

Cảm ơn trước ...

Answer 1

chỉ cố gắng tránh tải mỗi khi Execute Maven trong chế độ ẩn để tránh tải phụ thuộc mọi xây dựng của bạn đang chạy.

Nếu bạn đang sử dụng dòng lệnh, bạn có thể sử dụng -o làm đối số.

Answer 2

Nếu bạn đang sử dụng nhiều mô-đun maven trong một dự án, điều này có thể phù hợp với bạn: Tôi đang sử dụng Maven chủ yếu thông qua bảng điều khiển, vì vậy tôi không có kinh nghiệm với điều này dưới nhật thực, nhưng như Maven 3, Maven hỗ trợ song song xây dựng. Tính năng này hoạt động ra khỏi hộp, nhưng thành công của nó phụ thuộc rất nhiều vào các plugin bạn sử dụng, vì plugin của bên thứ ba có thể không được thiết kế để hoạt động theo cách đó.

Để kích hoạt song song xây dựng, bắt đầu maven với tham số -T:

mvn clean install -T 2 

xây dựng với 2 chủ đề.

mvn clean install -T 2C 

xây dựng với 2 chủ đề cho mỗi CPU.

Maven sẽ xác định thứ tự xây dựng và song song càng nhiều càng tốt.

Đáng buồn thay, nếu cấu trúc mô đun dự án của bạn là rất tuyến tính, tức là dự án A -> dự án B -> dự án C, điều này sẽ không làm bạn tốt.

Answer 3

Nếu dự án của bạn có các trường hợp kiểm tra, bạn có thể bỏ qua thử nghiệm của mình bằng cách làm theo lệnh.

mvn clean install -Dmaven.test.skip=true
