java.lang.OutOfMemoryError: PermGen lỗi không gian

Question

Tôi đã đọc tất cả các loại giải pháp cho việc này. Một link trong một chú thích trong

Dealing with “java.lang.OutOfMemoryError: PermGen space” error

là tốt nhất mà tôi đã tìm thấy cho đến nay. Khá phức tạp để làm theo mặc dù.

Vấn đề là, tôi nhận được lỗi này chỉ biên dịch một dự án với Maven.

Kiến thức của tôi không có máy chủ ứng dụng cho đến thời điểm này. Vì vậy những gì đang xảy ra?

Và tôi có thể làm gì?

Đây là lỗi của tôi:

Exception in thread "main" java.lang.OutOfMemoryError: PermGen space 

Answer 1

Xin xem câu hỏi này: "java.lang.OutOfMemoryError: PermGen space" in Maven build

(hoặc)

Xin xem liên kết này: http://vikashazrati.wordpress.com/2007/07/26/quicktip-how-to-increase-the-java-heap-memory-for-maven-2-on-linux/

If you get an error OutOfMemory error while doing mvn site, because of all the reports that you are generating, just increase the heap size for maven2. The way to do that on linux.

In your mvn.sh add this as the first line after the copyright and other comments.

export MAVEN_OPTS=”-Xmx512m”

note than Maven 2.0.6 onwards some users have reported that the double quotes give problems, hence you might want to use

export MAVEN_OPTS=-Xmx512m
