我试图安装天鹅常见此之后指南但天鹅常见罐子的制作(包括依赖)总是导致一个空罐子。 没有任何问题,安装Apache的水槽。 我试着增加了Maven的JVM按照指导内存,但这并没有帮助。

类似的问题是没有解决之前记录的要求。 对于这个问题给出的唯一建议是要么缺乏磁盘空间,内存或权限。 磁盘空间绝对不是问题,我增加了内存Maven的JVM和用户具有正确的权限。
编辑:
于是我就在mvn compile
在调试模式下通过@frb的建议,这是内存问题
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 257024000 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

我能够看到内存使用率超过70%时,过程被杀害。 该系统具有〜1.7GB,其远高于规定的要求 ,并且它是一个64位的系统。
我的系统内存增加至3GB和构建成功所以也许对硬件的要求应该更新?
