Combination of eclipse and Shell

When working in eclipse, you often need to open a shell or project folder. So today I found three plug-ins about eclipse combined with shell, PS, And the search will get far more results than the three, my general process is to find a satisfactory process and stop it. Haha, please let me know if there is a better one :)

1. shelled, a shell Editor, feels like there is nothing special, and I feel Vim is good. This plug-in is uninstalled because the other Java versions are later than 6.

2. wickedshell: visit his website. on the website, the shell is integrated into eclipse, and the shell script can be executed here. The idea is good, but the integration with eclipse is not very good. My experience is not directly more comfortable and powerful in shell, so uninstall and continue searching.

3. openextern. This plug-in is the simplest. There are some screenshots on also and homepage. Although it is rare, it fully meets my needs. I am using it now, but there are also some problems. In version 1.0.3, homepage says, need jdk1.5 eclipse 3.3. However, in my actual use, I found that JDK 6 is required, and it is useful in eclipse 3.3 classical, but not in eclipse 3.3 Europa version, I can't figure out what he depends on or why, so I am too lazy to do it. Use this first :)

PS:Eclipse shell script export plugin, put it here, and leave it to work out when necessary. The slow speed makes me very lazy. haha :)
