Linux 上 Eclipse 的 Java 路径设置

Question

我的操作系统是 openSUSE Leap 42.1。我同时安装了 JRE 和 JDK。以下是一些有用命令的结果。

void@linux:~> java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

void@linux:~> whereis java
java: /usr/bin/java /usr/lib64/java /etc/java /usr/share/java

void@linux:~> readlink -f $(which java)
/usr/java/jdk1.8.0_121/bin/java

然后我根据这个question的回答在Eclipse的eclipse.ini文件中添加了两行代码.

-vm
/usr/java/jdk1.8.0_121/bin/java

失败了。所以我用/usr/bin/java 更改了最后一部分。又失败了。这是第一次试验的失败:

JVM terminated. Exit code=1
/usr/bin/java
-Dosgi.requiredJavaVersion=1.7
-XX:MaxPermSize=256m
-Xms256m
-Xmx1024m
-vm /usr/java/jdk1.8.0_121/bin/java
-jar /home/emre/eclipse//plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
-os linux
-ws gtk
-arch x86_64

-product org.eclipse.epp.package.java.product
-vm /usr/bin/java
-vmargs
-Dosgi.requiredJavaVersion=1.7
-XX:MaxPermSize=256m
-Xms256m
-Xmx1024m
-vm /usr/java/jdk1.8.0_121/bin/java
-jar /home/emre/eclipse//plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar

Answer 1

我将 -vm 和 /usr/java/jdk1.8.0_121/bin/java 行移到了 -vmargs 前面。所以最后它看起来像这样:

-vm
/usr/java/jdk1.8.0_121/bin
-vmargs

所以它起作用了。
