我确信已经加了java路径到环境变量里了，/etc/profile，也能命令行使用javac和java，在ljudge/examples/a-plus-b里面运行如下语句
ljudge --max-cpu-time 1.0 --max-memory 32m --user-code a.java --testcase --input 1.in --output 1.out --testcase --input 2.in --output 2.out --debug
部分结果显示如下

我尝试指定java绝对路径到/etc/ljudge/java/run.cmd_list 即把原先里面的 java Main 修改为 /usr/local/java/jdk1.8/jre/bin/java Main
运行后依然错误 "testcases": [ { "error": "lrun exited with non-zero (14)", "result": "INTERNAL_ERROR", "stderr": "ERROR: exec '\/usr\/local\/java\/jdk1.8\/jre\/bin\/java' failed (No such file or directory)\n", "stdout": "" }, { "error": "lrun exited with non-zero (14)", "result": "INTERNAL_ERROR", "stderr": "ERROR: exec '\/usr\/local\/java\/jdk1.8\/jre\/bin\/java' failed (No such file or directory)\n", "stdout": "" } ]
我不是很清楚，是否哪里遗忘了 附上java版本 java version "1.8.0_11" Java(TM) SE Runtime Environment (build 1.8.0_11-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)
