java.security.NoSuchAlgorithmException：找不到支持Blowfish / ECB / PKCS5Padding的任何提供程序

Question

I have upgraded to jdk1.8.0_131 from jdk1.8.0_121 (jre as well) by uninstalling older and installing newer jdk and encryption code stopped to work.

Source code : http://docs.oracle.com/javase/8/docs/technotes/guides/security/crypto/CryptoSpec.html#BlowKeyEx

Error in eclipse :

Exception in thread "main" java.security.NoSuchAlgorithmException: Blowfish KeyGenerator not available
    at javax.crypto.KeyGenerator.<init>(KeyGenerator.java:169)
    at javax.crypto.KeyGenerator.getInstance(KeyGenerator.java:223)
    at com.encrypt_app.BlowfishKey.main(BlowfishKey.java:12)

Working without any error if run without IDE.

Steps I taken:

1. Went to Windows > Preferences > Installed JREs and changed Directory to C:\\Program Files\\Java\\jdk1.8.0_131 . Ensured Build Path setting of project.

2. Tried restart eclipse, clean, refresh project.

3. Updated JAVA_HOME to C:\\Program Files\\Java\\jdk1.8.0_131

-- Run same code without IDE and it worked.

4. Started eclipse with -clean argument (edited eclipse.ini)

Answer 1

从构建路径中删除库，然后使用更新的JRE重新添加。
