由于自己重新安裝了一下jdk,導(dǎo)致原先的JRE System Library 無(wú)法找到,后來(lái)在stack overflow上面找到了對(duì)應(yīng)的解決辦法,記錄下來(lái),給自己看,也給大家看看.

點(diǎn)擊項(xiàng)目的屬性(PRoperties),然后點(diǎn)擊java Build Path,選擇Libraries,如果找不到JRE System Library的話,會(huì)有提示nobound的,接下來(lái)的解決辦法是

Go to project then

Right click on project---> Build Path-->Configure build path

Now there are 4 tabs Source, Projects, Libraries, Order and Export

Go to

Libraries tab --> Click on Add Library (shown at the right side) --> select JRE System Library --> Next-->click Alternate JRE --> select Installed JRE--> Finish --> Apply--> OK.

然后會(huì)有默認(rèn)安裝的jre,再點(diǎn)擊finish,然后點(diǎn)擊apply問(wèn)題就解決了.
